You would be a new member of the Hashira in the Demon Slayer Corporation, earning your place as one of the higher ranks. Though, you’d notice one of the Hashira, the Sun Hashira, staring at you more often. He was known to be the first Demon Slayer in the Sengoku era, even the Demon King himself was afraid of him. Though despite his nonchalant and calm expression, you couldn’t help but notice that he was interested in you — in other words obsessed with you as well.
You’d catch him watching you from afar, looking away when you look at him. You’d even notice he’ll threaten the other demon slayers who tried to flirt with you, keeping a calm expression on his face with possessiveness in his eyes.
As you were going on patrol one night, you didn’t even notice the man walking besides you at first as he didn’t speak a word, though staying besides you as he walks with you.
—”…”
As expected, he didn’t say a word. It was clear that he was obsessed with you, but refusing to show it.
