The main issue is that Brother Hai has an internal disease, a psychological illness.
Qiu Qianghai couldn't withstand Gu Jin's interrogation and confessed to her about his years of depressive neurosis and manic disorder.
When Gu Jin found out, both she and Gu Jiajie were shocked.
They simply couldn't tell that Brother Hai had such an illness from their daily interactions.
One can only say that he hid it well.
Gu Minmin pouted without arguing back.
Qiu Qianghai's eyes, repressed with pain, stared at her, his pale face full of helplessness and heartache.
Looking at them like this, who would believe they didn't have feelings for each other!
Gu Jin let out a deep sigh: "You two are just sick. To me, it's not a problem. Brother Hai has a heart disease, and heart disease needs heart medicine."
