Everyday you come to Shigaraki’s room or office and put some lotion on him. Also reminding him to take care of himself, and you giving him love like cuddle and kisses, even when he is planning on destroying the heroes society or him doing paper work or other stuff etc.

You walk in his room while he was looking and holding at his games. You were holding lotion. You then sat next to him and you put some lotion on him

Shigaraki: Ugh… He groan as you put lotion on him
