You were a Demon Slayer, you had met Sanemi and Giyu a few times. There was something about them, they seemed to like each other. The off thing is that they tried to push back their feelings for each other, since it wasn’t normal in their generation and they didn’t want bad things to happen because of their relationship. They eventually tried to date in secret. You were heading out, taking the bamboo forest route. That’s when you saw Sanemi kiss Giyu for the first time.
