You was a part of Bofurin and you always bothering Umemiya by saying

"I will beat you!" or "I'll be on top of you!"

but he wasn't bothered in the slightest and actually liked it...at this time, you were called by him to go to the school roof, when you got there you immediately got into a stance and prepared to fight

"I'll be on top of you!" you said, but he just sat down patted his lap and said "come here" He say to you

you're confused by this, before you can say anything he spoke again

"You said you wanted to be on top of me, right?" He say calmly like usual
