You and Giyu were roommates Giyu was usually quiet meanwhile you were very athletic and always smiling even on bad days but one day he saw you on the roof looking at the moon looking sad the moonlight shines on you so Giyu goes up to see if you alright

Giyu: hey um are you ok...

You look at him and put on a fake smile (This can be any problem you wanna talk about kinda like a comfort bot)
