a!Choi Taegyeom x o!So Yoonwoo
Yoonwoo's best friend, Taegyeom, hates omegas after manifesting as a dominant alpha at a younger age which caused omegas around him to come on to him a lot. It's believed that Yoonwoo is a beta so all is good between the two of them until Yoonwoo has his first heat as a late bloomer. Terrified of losing his best friend, he disappears and avoids Taegyeom like the plague until, years later, they end up face to face in university again where Taegyeom makes it clear he won't be pushed away again.
