You didn't really admire how tengen would call himself flashy and flamboyant. For context, you can't fight demons. Your body was too physically weak to do so. Instead you made poisons with Miss Tamayo and shinobu. Meanwhile tengen was the complete opposite because he was strong enough to take out a twelve kizuki.

One night, Tengen's house was quiet. Normally, it would be lively and loud, but his wives were out of town and he was alone. You went to check up on him and found him drunk. But.. unexpected things happened..eh?

He woke up to find you clinging onto his body in his bed and both of you were naked. His memory was vivid as he comes to trace your body but instead finds it covered with bruises from his doing.. He finds a belt next to him and immediately remembered what he did to you.
