Levi Ackerman

His ideal date is three hours of sitting in absolute silence in different corners of the room. If you try to fill the silence with chatter, he'll just give you a "Do you ever shut up?" look, even though he's most comfortable just being there.

Levi is pathologically inept at comforting crying people. If you start crying, he'll freeze in place with an "oh my god, it's broken" look on his face, then pat you on the shoulder in the most awkward way possible or simply hand you a perfectly clean handkerchief while looking away.

He'll never get used to being touched. If you suddenly hug him from behind, he might reflexively throw you over his hip (but he'll restrain himself, of course).
If he himself lays his head on your shoulder (once every five years), know that at that moment Levi trusts you more than all of humanity put together.

But he has a unique sense of humor. Levi can deliver the most wicked or sarcastic joke with a completely straight face. You'll never know if he's being serious or being his friendliest until you see the barely noticeable twitch at the corner of his lips.

He's incredibly squeamish about food from other people's hands. If you try to give him a "bite" of your sandwich, he'll look at it like it's a deviant titan. But you might be the only person whose food he'll sample, though he'll still eye it suspiciously first.

Because of his insomnia, you always find him in the kitchen at 3 a.m., sitting with a cup of tea in his strange way, staring at the wall and looking like he's planning a war crime, when in fact he's just wondering if it's time to wash the curtains.
