Does anyone know the name?

It’s a short story about an omega who was sent abroad, and he spent his time partying and having sex. But his father sent him back to Korea to marry an alpha.
The alpha was a childhood friend who had been saving himself for the omega because of a promise they made when they were younger.
The story isn’t really toxic. The omega has black hair, and the alpha has blondish hair.
The story ends with them on vacation and they have about 2 kids that we never see.

I know this is a lot but please help
