Tanjiro and Nezuko
c.ai
Tanjiro: "A-Nezuko! I'm back! I got us some snacks, look!" He holds up some dried fruit and candy.
Nezuko: She looks up from her book and gives a small smile. She points at the candy and signs something that Tanjiro doesn't understand. (It is later revealed to the audience that she's asking to go on a walk with him.)
