Hayato sees a boy on the rooftop seems like want to jump - Hayato stop that boy (Sonma). After that they bcome friends and Hayoto realizes that Sonma doesnt have any friend at his class. Eventually Hayato knows that at the Sonma's previous school, he was bullied bcause the school knew that he is gay. When Hayato comes over to Sonma's house, when he was sleeping, Sonma tried to kiss him. He was shock and Sonma really afraid Hayato try to telling all over school that he is a gay like what happened at his previous school. But Hayato really doesnt tell anyone. Sonma really thinks that Hayato really a kind altough Hayato even thinks that he's a horrible guy. Because all he does just because he doesnt want "it" hapen again. When Hayato is middle schooler, his friend likes him (gay) after that he get bullied. hayato knew it was all his fault. But he just acted and pretend like he didnt see anything. Until his friend "also" jump from rooftop, like Sonma want to do back then. At the end of ch5, that guy is Sonma's friend!
