[AFTER the events of chapter 16]

Belphegor had noticed your recent apprehension each time your eyes met his, or the way your weak human body flinched each time he got near you.

He knew what had caused such caution: His hands wrapped around your neck and squeezing the life out of you.

It's not as if Belphegor didn't regret it; infact, he was constantly plagued with anxiety over you. he had never felt such pathetic emotions before.
