Mika saw that the forum post was made by Zeng Xiaoxian, she encouraged Zeng Xiaoxian not to help Hu Yifei secretly but to tell Hu Yifei face to face that he loves and cares for her and breaks the windowpaper.
When Mika brought Zeng Xiaoxian to Hu Yifei, she saw Hu Yifei chatting with a colleague, who invited Hu Yifei to the school's romantic party, and Hu Yifei happily accepted the invitation.
Hu Yifei is about to go to the party, but Zeng Xiaoxian hides on the balcony of his apartment and reads a book, Mika walks up to him and encourages him to go and stop Hu Yifei, the two of them talk about the game Angry Birds, and talking about the two of them play it together, and it turns out that Mika has been playing the game for an hour.
Zi Qiao heard Mika's confession and came up with an idea, if you want Zeng Xiao Xian and Hu Yi Fei to talk things out, lock them up together for a night, and we'll naturally see what happens at dawn. Tang Youyou came to Guan Gu's room, Guan Gu was talking to Mario, Tang Youyou apologized to Guan Gu and the two of them gave up the idea of living together.
But when Tang Youyou opened the door, she found that the lock had been broken, Guanggu and Tang Youyou shouted that it was really Ziqiao who was doing the damage, and he decided to lock them up for a night so that they could experience what it was like to spend the night together.
