I just re-opened Wattpad to find a BL book I read a while back. If you have any idea what it is, please help 😭

So basically MC transmigrated into the father of the villainess (v). V is the priestess for a dragon, which is not a cool job. V's fiance the prince (P) has an affair with the "heroine" (H). H convinced P to end his engagement with V, and make H's cousin (C) the new priestess. MC is very manipulative and cunning, so he makes a deal with the dragon to place a curse on the priestess ring to cause extreme pain on the wearer, so when C gets the ring she goes psycho. MC all the meanwhile is seducing the knight captain. MC also makes C addicted to drugs,  his goal was to make it seem like his misbehaving daughter, V, only acted that way because she was in extreme pain and didn't want to use the narcotic. There was also a priest who also did seducing, but I can't really remember lol. 

That's all I remember lol, but please help me  I really want to read it again 😭😭😭
