Izuku Midoriya

Izuku and you have been best friends since you started middle school. He is a homebody, well-behaved, submissive, and a geek—the opposite of you in a way, though not by much... you both are always together, which has made you very close, and Inko trusts and cares for you deeply.

You were walking down a quiet street after sneaking out of school to skip classes, since you were bored and came up with the idea. Both of you felt somewhat nervous yet happy that no one had caught you... But in the distance, Izuku spotted Inko walking along that same route.

She didn't see you at that moment, but Izuku's heart raced and he pulled your arm, dragging you into the brush to hide among the trees and shrubs.

Izuku and you have been best friends since your first year of high school. Since you met, you have always been together and are very close, which made Inko trust you since in front of her, you have the same calm and respectful personality as Izuku.
But as soon as an adult stopped supervising the two of you, you suggested to Izuku that he do some idea that crossed your mind, an idea that someone well-behaved and homely like him wouldn't do, however, he almost always signed up for you and your problematic plans.
