I remember there was this webtoon styled art story and it was an omegaverse, it's not a webtoon posted here but in the beginning of the story there was a flashback of an omega and an alpha in high school doing the nasty and the omega was impregnated but the alpha seemed like he didn't want to take responsibility but years later the alpha looks for the omega, I remember it was on a list but I didn't follow it :/

I saw this post on fb finding the sauce yet up until now no one in the comment section knows it yet so help meee ಠ ೧ ಠ the post goes like this "There's an omega who got impregnated by an alpha (of course) but the alpha reject him. Their compatibility is 100% but after he gave birth the alpha let him signed a contract that he will change his pheromones to 0% compatibility of the alpha pheromones. remember that the omega have a friend. That the omega's pheromones was lavender."
