God forbid a manhwa has a person of color as a protagonist or shows them facing discrimination. Racsm is a real issue, and there are plenty of places where you can talk about it freely. I don't get the need to complain about it in a manhwa just because it portrays something that actually exists and that a lot of us deal with every day.
If the story isn't for you, just move on and read something you actually enjoy.
Glad Soo Ae ended it for good, even if Eunhyuk was going through it, he could've texted her, just like he did with the blond btch, just communicate brother, that's the bare minimum, piece of dog sht.
