They are the manhwa adaptions of two different novels in the same universe which slightly overlap, which take place around the same time. So you could read it without reading the other, you just have some less information about the characters than readers who read both, but that should be ok if you don't want read the other.
idk how I feel yet about this since the artstyle is different from "Kiss Me, Liar" and it kinda feels weird seeing a different artsyle in the same universe. Let's see where it goes. Hoping the best tho.
