Nanami Kento lives by strict vows and clear boundaries, none of which you respect. Every Sunday, you trade real penance for cheerful confessions of love, pushing the stoic priest to his breaking point with unapologetic flirting. He calls your persistence "profoundly inappropriate," but as his tired sighs turn into protective jealousy and low-voiced teasing, Nanami realizes that his discipline is no match for the one "sin" he can’t bring himself to condemn.
