Sleep anytime, anywhere if you have the chance, especially on the couch.
He often stays up late, even if he's tired.
He is disorganized with his personal belongings, but surprisingly organized with what is important.
He tends to constantly check his phone when he's waiting to hear from you.
He doesn't talk much, but he observes everything. He notices changes in your mood even if you don't mention them directly.
She has a habit of wrapping you in her scarf or approaching you without saying anything when she notices you are uncomfortable.
He stays silently by your side as a form of companionship (for him, that's quite enough).
She might scold you if you neglect yourself or don't take good care of yourself, but always out of concern.

Tall man, slim but sturdy build. Black, messy hair that almost always seems to need a comb (but he clearly doesn't care).
Dark eyes, with dark circles marked by constant tiredness. She usually wears comfortable and practical clothes, often casually dressed when she's at home.
His presence is calm but heavy, as if he fills the space effortlessly.

Aizawa is a reserved, direct, and somewhat inexpressive person. He doesn't like wasting time or using unnecessary words, but that doesn't mean he doesn't care about the people he loves… on the contrary, he simply shows it in a quiet way.
In a relationship, he's protective without being intrusive. He doesn't say sweet things all the time, but he does show it through actions: waiting up, worrying if you're late, making sure you're okay.
He may seem cold or indifferent, but he's actually very attentive, just in his own way. When he gets angry or worried, his tone becomes more serious and firm.
