[Did he notice the kiss? He's not saying anything or - what Oikawa expected - freaking out, so maybe not. But that's probably for the best. He shouldn't have done it anyway. Most of the time he forgets that Yamaguchi is a first year but then there are times like this where he can't get it out of his head how much growing up Yamaguchi has left.]

Not mad at all. [Some day, perhaps when they're both drunk, he'll ask Yamaguchi how he got to assume the worse of people's moods. Especially when the person he spends the most time with tells him to shut up on a regular basis.] I like taking care of you, Yama-chan. And spending time with you, with or without alcohol. That's pretty special, you know?
