The night was full of stars. The night wind carried the scent of trees on the school grounds. A car drove up. The person who got out was the school director. He had returned to the school, checking his watch as if confirming an appointment. He told the security guard that he was there to retrieve a document. When he entered his office, he opened the door and saw the office chair turned backward, swaying gently as if a person were sitting and rocking it slowly. We could only see the person sitting, pressing the chair with a hand, and seeing slender legs crossed. A voice told the director to sit properly on the sofa. The voice and appearance clearly belonged to a woman.
"The results will be shown soon, and all the teachers will be calm." "Yes!"
A sigh was heard, followed by a reprimand to the director for not cooperating well enough. "Watch your behavior, Director. Don't worry, the results will not disappoint! Please tell me what you have prepared for " She handed him a document. The director took it and looked at it, exclaiming, " have to choose her? But she is the diamond of our school!"
"Our school?" She asked, "Then what do you think about that matter, Director?" The director was speechless, then bid farewell and left, slightly angry but forced to remain silent and obey.
Who was this woman? What was the matter? She wore a mask and stared into the camera before walking out.
The next morning, kan came to school early and went to find vud. She was delighted to receive his agreement; now she had someone to go to meet Pud with. However, vud forbade her from telling Hav. Why would I'm tell Hav anyway? He seemed uninterested in my investigation. They set a date for their mission to find that person this Sunday. Vud admitted he didn't know any information about that person. Then she told him not to worry; she knew whom they were looking for: San. She said San's name in her thought.
When they parted ways, kan hadn't written the lesson for Jin for a long time, so she went to the library. There, she overheard Hav's subordinates discussing that the person who paid them a lot of money had asked them to meet on Saturday. They spoke loud enough for kan to hear. She decided she would go and follow them that day too. Just then, Tan came up behind her and walked past. She immediately saw him and followed him to the supply room where Tan usually rests. When she opened the door, she saw a few Grade 10 students bullying tuna and insulting her as an orphan. She saw this and was about to intervene, but saw Tan step in first and threaten the Grade 10 students! Tuna thanked the senior, while kan hugged and comforted tuna, telling her not to be afraid. Tuna was truly scared, even though she was constantly being bullied. At that point, Tan told the two of them to leave the supply room; he needed to rest. Kan was very annoyed with Tan.
We see kan holding Thuna's hand and wiping her silent tears. "Why didn't you ask me why they keep bullying me?" kan sat down and sighed, saying she wanted to ask, but was afraid tuna wouldn't be comfortable. Kan then explained that if tuna needed help with anything, she had vi, who seemed to be her close friend, and always worried about her. Tuna was quiet and said she only wanted to die, but seeing vi always worry made her continue to stay and study.
Kan told her she didn't know how big the problem was that made tuna so afraid of them, but if she could, she should hit them back; at least she would have fought! Tuna laughed, and her smile was very beautiful. She complimented kan on being funny. Then, she said she couldn't tell kan about the matter, but just having kan and Vi watch over her nearby, like now, made her feel somewhat relieved. Kan said tuna could tell her anytime she wanted. Then they parted ways.
Kan arrived at the library and told vi about her conversation with tuna. When the librarian returned, they stopped talking, fearing the teacher would find out and cause more trouble for tuna. The teacher asked is kan was looking for a book again? Kan denied it; I was just there to write notes for someone.
Taking a short nap in the library was kan's bliss. When she opened her eyes, she saw someone standing in front of her holding a ball was it San? She rubbed her eyes, realizing it was just her imagination. She rushed to her class. On the way, she met San, and the two went to their respective classes.
We see Dan arriving at school the latest, standing and looking at the school as if deep in thought. He then went to the teachers' office and headed straight for Teacher phan that is kan's homeroom teacher. Mutu, the class president, saw him talking to their teacher. He put the phone away and was called over by the teacher to stand and listen. Dan was confessing his mistake, carefully choosing his words so it sounded like he was truly the one who broke the window.
"Teacher! Actually, I was the one who broke the window!" The teacher was surprised and asked, "Why did you just come to confess now?" "Because I didn't dare, but now I think it's wrong to hide it." The teacher told Dan to go back to his class for now and told mutu to inform the classmates that the person who broke the window had confessed, without mentioning the name.
Kan and everyone heard this and were confused. Did it was Dan who confessed? If so, Kaan would be extremely annoyed with Dan for confessing.
Meanwhile, Dan was resting his head on his desk. When his friends were playing, they received the news that Class 12B had found the culprit, who had confessed, but they didn't know who it was. San and his friends were also curious, while Mai stared at Dan as like she knew it was him.
During the first break, kan sat in class, wondering why Dan confessed. Hana saw her like this and came to pat her shoulder, saying, "From now on, you won't have to worry about investigating anymore, because the culprit has confessed!" ,"Hana, we both know he didn't do it!" Siv siv asked, "Who are you talking about? Do you know who confessed?" The two denied it simultaneously, saying they didn't know, just talking. Hana suggested, "Exams are coming up soon, kan. You should focus on studying instead." kan agreed, though she was still uneasy.
The students returned to class as usual, everyone eager to know who had just confessed. They asked mutu, but mutu replied that he didn't know, as requested by the teacher.
Physics class again! The teacher was teaching and asked, "How's your investigation on the broken glass, kan? The culprit has confessed, are you still investigating?" kan stood up and replied, "I don't know either." She was about to say more, but Hana stopped her in time. During the second break, Hana scolded her, "Why can't you control your emotions, kan? You want to help Dan, but Dan has his own way!" Nevertheless, kan went to the teachers' office. She saw the school director was angry about the culprit who broke the window glass. He said he wouldn't be angry if they confessed immediately, as it was a small matter, but lying for so many days and then confessing showed a lack of responsibility. "Deduct 50 points from him!" kan walked in and said, "It wasn't Dan, Director!" The director turned to her as to listen. All the teachers were listening too! She continued, explaining everything she knew and her suspicion that someone had broken the glass intentionally from the inside. "But that day, I don't know who was in the class with me or behind me, or how they broke it. I haven't even checked the class camera yet. But at first, I wondered why my vice class president told me the teacher checked the camera and said I was the last one out? So, if the camera was working, why didn't the teacher check it and show it?" Teacher phan said, "Who said the camera was working?" kan realized they had lied to her to make her investigate alone. Teacher phan said the camera had been broken for a long time and hadn't been fixed yet. The director pretended to get frustrated and said, "Deduct only 30 points from him!" kan insisted, "But he really didn't do it, and he confessed on behalf of that coward? Teacher phan explained, "But he kept silent and didn't take responsibility, and your video shows him throwing the ball." However, the director said, "If kan says so, if you find the real culprit, I'll only deduct 10 points. But if you continue searching, you must do it secretly. I don't want the school to be chaotic many times." kan had no choice but to agree, as she felt sorry for Dan and also wanted to know for sure who the culprit was and what their motive was. She muttered, "If you don't want chaos, why did you let me investigate in the first place? Just fix it, and the matter would be normal." Her soft words were heard by Teacher phan, but he didn't say anything and told kan to leave. She walked back, passing by Dan's classroom. The teacher there announced that the student who confessed would have 30 points deducted. Everyone wondered who it was, saying 30 points was a lot, and the student would fail. Kan looked at Dan from afar, seeing him asleep. She smiled at San and walked back to her class, where everyone knew about the large deduction.
Leaving for home, kan told Hana that she would investigate again and find the real culprit so Dan wouldn't lose too many points. Hana didn't say anything, which made kan realize Hana didn't want her to continue investigating because she saw kan wasn't focusing on her studies. Kan told Hana not to worry; she knew that, but she also wanted to help Dan! Hana asked, "Help Dan, or find out who ordered Dan?"
Kan smiled and teased Hana to make her laugh. Then, she asked is Siv siv was okay? Hah? Orr ! "Nothing is wrong!"
Mala came and asked who broke the window. Kan replied she didn't know! Mala was furious, thinking kan was mocking her! But mutu intervened, saying the teacher asked to keep it a secret, and the confessed person was someone kan didn't even know, who just came to confess themselves!
In the evening, kan worked as usual, chatting and laughing with sister Khai to create a cheerful atmosphere. Suddenly,she asked, "Why are you looking for the old book that San asked you to find the other day, sister Khai?" khai seemed to freeze and didn't want to tell her. Her sighed and lied that she just liked old things, especially books.
Back home, we see khai carefully opening the book, afraid of tearing it. Tears rolled down her cheeks, and she hugged the book without saying anything.
<--->
The day kan had been waiting for finally arrived; it didn't take long, but kan was impatient for Saturday to come.
The two met at the four-way intersection. She walked towards vud, and she was the one leading the way. He just followed and trusted her. They arrived at a quiet road and saw a man squatting and smoking. Hearing people approach, he turned around. It was Pud.
