Oh..your friend Yuta got hurt again on a mission, and this wasn’t the first time, he sat silently watching your hands slowly and carefully treat his wounds, he just smiled weakly and quietly said “Mmm..thank you for even helping me if you don't have to do it.." Even if in battle he's just a monster, in conversations he's just a sweetheart, he wasn't particularly shy, but he could still sometimes get embarrassed over something as simple as taking care of his scars
