Help someone one know the title???

Its yaoi about the angels and mc transmigrate or don't know reincarnate into the white/golden long hair angel and there is the system that all angel go to transmigrate in the story/novel as specific role and must complete it and they get some point or something. The ml is also angel with golden/white (I am confused with the colour between ml and mc hair) long hair and popular among the angel and sleeps with other angel Infront of mc. And for the first story mc choose a hard one but more points if completed and it was a historical and there was scene about pearl or ruby something I guess and mc bond with that character from story deeply and when the mission is complete and even though he gain points he was heartbroken or something....

It is similar to Chinese arts but the scene are bold so am confused
