Guys, can someone help? I'm trying to look for a yaoi manga that is a one shot (?). The setting is not historical, and there is a church where the mc is like an apprentice (?) so he works there. He is in love with the priest who raised him since he was a child, so there's an age gap. The priest has a long white hair, cold personality, and is muscular (?), but I forgot about the mc's appearance. Then I think the mc (bottom) drugged the priest with aphrodisiac, and although the priest try to control himself, IT still happened. So it's basically about smut. Pls, I hope someone knows the title, I can't find it anywhere
