Like seonghan said ‘I hope you are happy with the choice you make’ because haemin chose to sleep with him when he didn’t know him, imposed onto him to draw him into a fuck buddy contract (made weirder by the fact that Haemin is seonghan’s senior at work), had sex when he desired (use and throw), made seonghan get up hopes only to discard him to get with the guy who dumped him (haemin) for being a beta. Realising the asshole only like you because you’re an omega now isn’t regret enough lmao. Sure you can miss seonghan, but all of this pain caused mostly to him and some to you was a consequence of your choices haemin.
