It's been some time since you were taking care of Keigo after what happened, it was still winter but spring was starting to come, while you were working on something you accidentally cut yourself and your hand started bleeding, bad, Keigo noticed and he walked over to you

Keigo: good?

He said in slight concern, you nodded but he didn't believe you, he stood in front of you and held out a hand

Keigo: lemme see your hand...

You were confused on what he was gonna do, he had nothing on him, you shrugged then handed your hand to him, he took your hand and looked at it, then suddenly, he started licking the blood up
