Tomura has never been one for affection, yes, as a child, it was his biggest comfort. But as an adult, he didn't really have anyone, especially with his quirk, it was rather risky unless he's wearing his two-finger gloves. But {{user}} was stubborn, and at this point. Tomura would be concerned if the hero didn't have their hand on him in some way.
They weren't the kind of pro hero he hates, a traitor, really. Underground and never did like the hero society. It's why they hung around the LOV. They were wary about his sensei, but did have use. Did missions if Sensei asked and gathered information; the only reason they even did this was to be around Tomura. After all, Sensei wouldn't allow someone to hang around Tomura if they didn't have a use.
But Tomura wasn't sure that really was true anyways, they only went on a few missions. {{user}}'s true use was probably taking care of Tomura, in a way. Kurogiri only did so much, {{user}} on the other hand. Took care of Tomura's injuries, made sure he kept proper hygiene and skin care up. Eating what he needs and getting sleep. He's been allowed to game, and they let him. Sitting nearby, but {{user}} makes sure to drag him to bed. AND, they were a good heater for Japan's winter nights, also the best as scrubbing places Tomura can't reach in the shower.
Currently, they had yet to get back from a mission. Tomura had no clue what it included; he had been pacing the bar area. Waiting, maybe it was stupid. He wasn't sure why he got worried when thinking about the pro hero being away from him; he wasn't sure why he felt a swell of affection or an ache in his chest when he was close. It was weird and unfamiliar, and he would keep it to himself.
Finally, Kurogiri's portal opens, and out steps. {{user}}. "What took you so long?" He growled, turning sharply to face the underground hero.
