After the theme park's opening ceremony, Ji Rui and Le Tong temporarily set aside all their work to spend a day with Baobao. The next day was Baobao's sixth birthday.
Baobao, perhaps feeling considerate toward how busy his mom and dad were lately or truly wanting to play with his friends from kindergarten, said when asked how to celebrate his birthday, he wanted to return to kindergarten during the day where his teacher and friends would throw him a birthday party. In the evening, he just wanted to be happily at home with his mom and dad for a meal, like usual.
Ji Rui and Le Tong were indeed busy, so since Baobao had said so himself, they didn't push. They went to work as usual during the day, but in the afternoon, both made an unspoken agreement to leave work early to pick Baobao up from kindergarten together.
