Yuni got fainted. Tae saw this and informed the police. They took Xiao to the polive station.
Xiao told his reason why he tried to hit Yuni. The main reason of his hidden story ----
Xiao was actually a biesexual.He had weak feelings for Tae. Every girls in the class always appreciated Tae. Xiao was kinda jealous of that. Xiao and Tae used to be very close friends. One day, Tae told Xiao that he loved Yuni. So he was working hard not to fall from his position in the school.He started to study more. So, he stopped to join in gossip and playing basketball. He started to give Xiao less time than before. Xiao got worried that he loved Yuni. That thing started spinning round his head. Why couldn't Tae saw his love towards him. One day when Xiao was about to give Tae chocolate, the same chocolate Yuni gave Tae and Tae was quite Impressed by that. Xiao hid his chocolates behind himself. Xiao was getting hyper day by day for Yuni. He decided to erase the instinct of Yuni. He also planned to make Tae a suspected person as he thought that Tae rejected his feelings indirectly.
So, one day in break, he told Ken that Tae wanted to have a look on his glasses. Ken gave it to Xiao. He took the glasses but in return the glasses he gave to Ken, their power was quite different from Ken's spectacles.From then he was not able to see things around him properly. He thought his problem of his eyes increased than before. So he started to use contact lense from then.
