Im looking for a bl manhwa i read last year. It's set in europe and its completely in black and white.

The MC is a nobleman with black hair, and he was friends with a nice doctor who gained a noble title through his work. The other nobles didnt like the doctor, so they assassinated him and his entire family (this included his wife and 2 children), but years after their deaths, the MC finds out one of the children (a blond boy) actually survived the attack. During the assassination attempt on the family, the MC's fiancée was killed in the town square after being tried for some crime too, so he didn't make it in time to witness anything in regards to the family, but he found it strange how one of the children's bodies was never recovered, it turns out it was because the kid had been kidnapped by some other guy and was being hidden in his home the whole time.

In the present timeline, the MC and his allies ended up finding the boy and saving him,

I dont remember much else, but please let me know if this rings a bell!

I'm looking for this omegaverse manhua: The characters were students, the MC had purple hair and grape scented pheromones and the ML was a red head and I think his pheromones were tequila scented. The story was kinda slow paced and mostly just about their school days
