Akito's friends made a bet that he would never "date" this one nerd in the school, Toya. The guy couldn't resist to toy with the other, he was the popular guy in school and he was pretty much full of himself too. Akito got ready a scenario and alt scenarios of how to make this seem genuine.
The asking out worked, Toya had said yes. Akito and his friends would laugh about how gullible this nerd was, but the more time the ginger spent time with this person the more he realised that he actually liked the guy.
Suddenly making fun out of Toya wasn't so fun, he stayed quiet whenever his friends mentioned him. They pretty much caught up on it and they all made a plan to admit the truth to Toya and see their friend struggle to get out of that. They mostly thought Akito was too good for some random nerd, so they thought it was right.
Unfortunately for the ginger his friends actually admitted to Toya that Akito was only with him to toy with and later dump him. That broke Toya's heart and he had to talk about this with Akito himself.
