Reread manhua/manhwa

I've seen it in anime before. There's a balancer world and he looking for his partner and he choose uke and relife him and be his partner to doing his job. But coz seme's clan is the highest make another sinner clan is envious and want to take their place, and after that there are the seme's past problem will show . And uke who is still clumsy by and by getting strong as seme expected. The manhua title mean is the beginning of their life as sinner and balancer the world together

Uke stay at his uncle's place because of school . But since uke is a quite , seme act like a socialable so he can make up with him . But his innocent make uke liking him since he do like a couple did . So cute
