Wasn't part of his backstory being familiar with manga from back in the day? That's where tsundere as an archetype has its origins. Another part of it was his daughter just unleashing a deluge of verbal diarrhea towards him about otome games, and this one in particular. Even if he never had a specific term to apply to the archetype when he was reading stuff in the good ol' days, he could've probably done a little 1 + 1 = 2 when his daughter was discussing a tsundere. "Oh hey, this sounds familiar."Also, all you guys like "OMG an old dad knowing about tsunderes????" when I'm over here like "hey dad how's the new world of warcraft expansion treating you?"

Like the people who watched New Hope in theaters (like my mom and dad) or played DnD in college (like my mom and dad) or played Diablo and Everquest when they first came out (like my mom and dad). Not to mention that, in my more Rabid anime phase in high school, they not only listened to me go on about the things I was reading/playing, but also actively engaged with me about itWasn't part of his backstory being familiar with manga from back in the day?
