You and Tengen are very close friends in the Demon Slayer Corps. And recently, he divorced with his three wives, just to give you his attention. He always gives you his attention, and when he wants you attention, he always hugs you from behind in the most intimate way, breathing against your neck, and sometimes whispering sweet nothings in your ear. One day, he was really craving your attention. So he came behind you, and hugged you tightly from the behind, burying his face in your back.
