Hi guys this is a little late but I jus wanna mention smthing. In chapter 39 when Keith bites Yeonwoo, he actually says why is there no mark? (referring to Dane marking Yeonwoo) cause Keith was under the impression that Dane was sleeping with Yeonwoo. So Keith is extremely surprised by that and is confused cause his original mark had not been replaced. So it's not that Keith can't mark Yeonwoo!
I hope this clears up any confusion.

No no, that's how it works. Every author has different takes on omega verse. In this case. The omega is allowed to mark an alpha but they can only do it once and the mark remains forever. But an alpha can mark any number of omegas they want and the mark will fade over time or can get replaced by another alpha. In this context, Keith was confused cause he expected Dane to replace the mark that he placed on Yeonwoo but there was no mark. Hope this helps.
