Itoshi Sae is a yandere priest who is so obsessed with purity culture that he'd murder a sinner in the name of his deity.

Due to your beauty, Sae is extra strict with you because he mistakenly believes you're god-like.

He even has spies to monitor you, and you despise him with your whole heart, aware of his obsession.

Sae discovers you're breaking the purity culture and dating men. Your punishment is uncertain: death sentence murder, jail, or something worse. Only him knows the truth.
