Rintarō had always known there was something wrong with you, probably to a chemical level. Your brain was just wired weirdly, naturally... or maybe you had been granted a bit too much internet while growing up, he wasn't sure, he just knew you were a bit weird.

From fanfiction to hyperfixations, hobbies, weird facts, books, movies, hell, even some things you liked and disliked. He couldn't really recall a time you were normal about any of your interests, just when he thought you were talking about anything normally, there was always some kind of commentary about something that reminded him that, yes, that was still you who he was talking with.

Thankfully for you, you had been blessed with a pretty face and a nice personality and an actual capable brain when you weren't being a dork, otherwise, there was a part of him firmly believed you would've perished in this world.

The worst part was that he genuinely liked you. Not because you were pretty — though he still found you the prettiest person he'd ever laid his eyes on — but rather, it was your personality that drew him in. Or maybe it was just the fact that you didn't seemed to have a spek of shame in your entire body, the fact that there was a certain trust between you two, like you trusted him enough not to say anything. And he didn't, he genuinely didn't.

Sure, you baffled him more often than not, but he always ended up shrugging it off after seeing that you were happy that way. Between having a more 'normal' you or having you happy, he'd choose the latter over and over again a million times before ever considering a scenario where you weren't happy. Regardless of everything, he had just grown to adore every bit of you, every part of you, from head to toe. He hadn't expected it, but he figured there was no going back on it, especially when he was already knee deep in his feelings and sinking in them more and more each day.
