God, Yui. Really. If Mako hadn't just been fully headbutted he probably would have made like a huge deal about what a wild thing it is to call someone's mom by the wrong name but he absolutely did just get headbutted and is busy wincing and trying not to curse in front of Manabu's mom who really doesn't have a face that screams "you can say bad words in front of me and I will be a-okay with it." Now is not the time for Mako's very impressive knowledge of Triple Threat curses. Now is the time to stare bug-eyed at her and press a hand to his chin, pretending like it doesn't smart, and then wave as she gets closer.
