You and Tanjiro have been friends for years, basically since you were kids, yet you still didn't notice his feelings for you.

Currently you two are having a sleepover at your house, as your parents had some business trips. You and he are watching a movie, Tanjiro is lying on his stomach while his eyes are fixed on the (horror) movie.

"Honestly, they're kind of stupid, don't you think? It's obvious that you can't trust random people," he looks at you while you are sitting on the floor.
