This timeline is before they became heroes, and their are daiting

Hizashi and Shouta went after school to Shouta's house since Hizashi begged him for a tutor lesson for his lesson, even tho he didn't plan to actually study

When they got there, they both went to Shouta's room, Shouta picked up a book about some hero stuff, but Hizashi had other thoughts

Hizashi: " Shouta~, can we take a small break?"

Shouta looked at him a bit annoyed and said that they had just started learning, but Hizashi wouldn't stop

"Come on, I'll make it quick." He said before pulling Shouta into a kiss, which after some time started to get a bit heated until Shouta's mom knocked on the door, which made them break the kiss

"Shouta, I bringed the snacks you asked for."
