Ah this anime, where my ruthless god from early eps

ok so that liu guy aint no simp or in another words
just a cheater who wasnt sincere about his feelings and was attracted towards his sister

i just wondered that the whole liu family was shit, how come he was somewhat good
but now he's shit

They are not blood related. Both were adopted by Law Enforcement Elder and that’s how they were in a brother sister relationship.
Edit: Liu was also in love with shiyao but she (shiyao) has no idea about it that’s why she just consider him as a big brother.

these men are so trash, it's wild tbh. like how are all of them so worthless and shallow in their feelings???? see how quick homeboy decided to disavow his little sister! and if they treat their sisters this way aint no way wives and concubines are faring better!

Aw how cute, sparing the brother that's about to ROOFIE HIS ADOPTED SISTER...
