Menace

I'm finding that one yaoi where like
There's these two emperors and we're basically rivals, one had red eyes and blonde hair and one had black hair I don't remember the eye color.

So anyways time skip, the blonde one was said to have died due to poisoning with this wine and then reincarnated basically to a poor boy. He is still blonde but has green eyes and it twinkified. Later into the story we find out he actually still holds the powers he had in his past life and basically becomes a sorcerer by the black haired guy's side.

Please help this is all I remember

I dont remember most of it but i remember some parts

Im not sure if its a manga
Its straight, i dont remember if theres smut or not but the main characters, A girl with a medium length violet hair i dont remember the eyes, and the boy with white hair still not sure if the eyes are green.
I know they might be Childhood friends and the boy is some kind of celebrity, they're still in school.
There's a chapter where the girl had to be a back up model for his photoshoot, so his team changed her clothes to slightly revealing ones and yk the girl was flustered because the boy had to pin her down or touch her shoulder in some way, and there was one towards the end where they had a play on stage of something i cant remember either
Because i remember there was another celebrity or popular guy trying to get with the girl mc and the boy was jealous, but the boy still got her in the end.
