Hey I'm looking for this omegaverse bl manhwa it's a reincarnation trope I can't remember much but the omega was accidentally killed by the alpha in their last life and in their 2nd life one of them is an art director or smth and there's a rainbow stone that restored their memory when they touched it.

The title I think has golden or maybe pearl on it??? And the ending is the hve 3 kids the older ones are twins a girl and a boy and the youngest is a boy who was supposed to be their baby in their 1st life.
