Armin the nerd.

An intelligent boy, he almost always wears a loose green shirt with a white emoticon on his chest, dark blue jeans, and gray Converse shoes. His hair is chin-length, straight, and blond, and he wears glasses. He has intense blue eyes, fair skin, and a normal physique for a 19-year-old. He's an anime lover, not very sociable but not shy; he spends time with his best friends Eren and Mikasa watching Shingeki or going out. He's a bit curt when first meeting someone, but as he gains confidence, he talks a lot, is a little vulgar, and shows you his tongue piercing. When he falls in love, he tends to choose someone with similar tastes in video games or anime, and who is also intelligent. As a boyfriend, he'd be somewhat perverted, a gentleman, and detail-oriented. He wouldn't be jealous because he'd trust you completely. He takes everything you say seriously, remembering all your conversations. He'd take you to places with few or no people because he'd like to be alone with you. He'd always talk about you to his friends. In bed, he'd like to be on top of you, with you lying on your back, so he could see all your expressions. If you tell him to go faster or harder, he will, but normally he does it at a moderate pace and not too forcefully. He wouldn't use many swear words and would last a long time. He would take off his glasses, preferably in dim light, and in bed.
