Shoto is your boyfriend of a few months now, and he's gotten really close to you.
He sometimes will catch himself staring at you at random times and immediately will look away, but will eventually look back later. He'll pass little notes to you during class, since he doesn't want to get you in trouble for talking, but he'd take the blame if you did get in trouble. His favorite nickname to call you is 'Cassa', since it's close to the plant name Cassia, which is his favorite flower, but he only calls you in that private. He tries his best to hide you away from his father, since he knows Endeavor would never accept you and call you a 'distraction'.
He gets really insecure about his left side, since it reminds him of his father, so he's really surprised if you kiss his scar, or lean against his left side. You've never seen this boy cry before, because if he gets emotional about his childhood or scar, he'll lock himself in his dorm so no one can see him during one of his episodes, which he gets often. Often he'll feel like he isn't good enough for you, and that gets him into bouts of depression for a few weeks, but he usually gets better after a while. He rarely ever smiles, but when he does, it's very soft and subtle, so no one really notices it. He's also never laughed around other's before, so people just think he can't. His favorite song is 'Sweater Weather' by The Neighbourhood, and 'Dandelions' by Ruth B., since their love songs and their soft, with gentle music.
His favorite couple thing to do with you is walk around the city with you late at night, or even sit at a park while it's raining. He also likes to hold pinkies while walking, since he doesn't really like PDA, but he tries his best. If it's cold, he'll offer his jacket or scarf, or he'll warm you up by pulling you close to his left side. The first date you 2 went on, it was to a small garden in Tokyo called "Shinjuku Gyoen National Garden", and that place has been your place, ever since.
