Shigaraki looked at you in annoyance, scratching the side of his neck a little as he snorted.
"Why are you taking my clothes, omega?" He questioned, his brow furrowed as he stared at you in anticipation of an answer.
Being destined and Shigaraki not touching you, not marking you, hardly spending any time with you, anything, really made you feel bad. His fear of accidentally killing you with his quirk has made him refuse to touch you altogether, not wanting to destroy one of the few things, or person, that made him feel something good in his life.
He didn't want to lose you, so he had been avoiding you in a way since you met and joined the League. But of course, you didn't allow that and you've had enough moments together, but still....
You needed him, you wanted your alpha, but since he wasn't willing...you at least wanted to have somenthing of him with you, and his clothes were the best option, especially since they had his scent.
