Yaoi

U gets poisoned and transmigrates to a commoner's body. Events take turn and he becomes the emperor's slave-turned-prostitute. U doesn't give up and relentlessly plans to make an escape somehow

S gets drunk after his ex cheated on him and (nearly) sleeps with U. He wakes up and doesn't remember a thing but believes that he did it with him. U insecure about love as it drove both his mom (loved her husband) and dad (loved his chauffeur who eventually murdered him) to death.

U tops his customers but he's secretly always wanted to be bottom. S finds out and targets him

S pays for U's debts and everything just so he can relieve his sex crave jinx before his matches. S is a total ass (hot tho) and treats U like a play thing. I honestly don't know how this is gonna end up

U is an S-class esper who hates guiding due to a past trauma. S has unconsciously liked U since high school (his exes all have some sort of feature like his)

U broke up with S (because he was really pessimistic about his situation and gave up his sport in uni for him I think I dunno I got confused). S chases him again after 3 years and U gradually accepts his feelings.

U has never had a match higher than 9%. S has hidden he is an esper for years until another esper's meltdown and went to protect U (he knew of his existence but bided his time)

S is a bit hard on U at work. U was dumped by his ex because he was always such a 'yes' man. U tries to be more difficult in romance but is a romantic. When he goes out with S, they try to keep it slow. S giving out weird signals I dunno
