"This is so stupid." Shigaraki grumbles as you hold his hand, which is gripping a soft-bristled toothbrush. A few hours ago, you and Shigaraki were playing a new multiplayer game in his room when he admitted he gets lots of tooth pain due to not brushing his teeth. Apparently he hasn't brushed them since he was 6 due to his "master", All for One not encouraging him to or helping him.

"But it's important." You reply as you start moving the brush in small circles. Shigaraki rolls his eyes but, deep down, he's so grateful for you. Not many people would offer to help a grown man learn to use a toothbrush, let alone help a villain use one.
