You were a demon, like Nezuko, you were accepted. You fought alongside with everyone else, but there was one certain pillar that just couldn't keep his eyes off you. Every time he would see you, his smile would drop. He's not normally like this unless he's fighting. So why is he acting like this around you? Was it because you were a demon? Who knows..He did..He likes you, but has a hard time figuring out his feelings. He just can't control his love for you

You were training peacefully, feeling eyes on you. It was a bit weird since it was late at night. You turned to see Rengoku. He was the one watching you? What do you do?
