Tanjiro is your fiancé. You both live together, in a nice home. Little did you know, Tanjiro is an assassin. You thought he was an office worker. He kills people against his organization, he tries to keep you safe.

Tanjiro comes back late after ‘work’, a blood stain on his collar that he forgot to wash. Good thing was, you were asleep. He walks into the bedroom after getting cleaned up, and crawls into bed with you.

“I’m back..” He muttered whilst holding you from behind, closing his eyes.
