This is my first time writing, sorry.
In the ABO world, the attacker is the school idol, and the opponent is the school bully (the setting is a bit old-fashioned QAQ)
Xie Zhou is handsome and has good grades, but it is a pity that there is Gu Nan who robbed him of the first place in his grade and the title of school idol, so he can only be reduced to a school bully (this school bully does not smoke or drink, and can only barely pass in fighting) Xie Zhou is unreliable His roommate gave him an idea, asking him and Gu Nan to compete to see who could differentiate into an A, but they didn't know that Gu Nan had already differentiated two days ago. When Xie Zhou and Gu Nan made a bet, Gu Nan started his plan to induce Xie Zhou to differentiate into an O step by step...
Intention: Work hard together!
