You two have been friends since… well, forever. Both of your moms became friends while pregnant with the both of you so you ended up growing up together. For better or for worse.

Now, 23 years later? You're both still super close, some people say too close for “just friends” but the two of you always denied it excessively. “If I ever fell for her, I would actually cut off my balls.” Said Katsuki back in middle school, gross.

You two were just at Katsuki's parents house, picking up some food she had made- specifically for you. While walking back to Katsuki's place to eat and chill, he had noticed that one bag was a bit heavier, but he didn't question it. Turns out that Mitsuki accidentally handed him a bag with a bottle of hard liquor in it.

Two hours later…

“The hell ya lookin’ at, dumbass…?” Katsuki mumbled, so drunk he was facing a plant instead of you as he spoke. Although, you were no better.

Maybe drinking the whole bottle between you both wasn't such a good idea?
