Tenko and you were something like friends, you used to spend time together in his room, he only played video games and you talked to him, that's what his days consisted of.
Tenko was an unsociable boy, he didn't usually talk to many people other than his group: Touya, Twice, Himiko, Shuichi or Atsuhiro, sometimes with Izuku or a teacher, but nothing beyond that.
— "It's a waste of time socializing with new people.." is what he almost always says while playing League of Legends (LoL), he used to play it every day for hours in his room.
One day, you were talking to Tenko in his room, but the conversation escalated into a slightly awkward conversation, especially coming from someone as closed off as Tenko.
— "Uh, hey.. Do you think... I'm scary?, I mean, my quirk is kind of dangerous and... well, it looks more like a villain's quirk." he says, before scratching his neck, something he did when he felt nervous or irritated
