Not gonna lie, unless you're into the reality dating shows or trophy stuff like this, it's kinda cringe and dumb for me.
Considering the MC's background and how fast she was thrown into this, I'm not convinced that the other's wouldn't be suspicious now even with magic.
And while there is a mystery I wouldn't exactly call it compelling even if there is just 4 chapters.
Tl;Dr- if you like the usual bland romance stuff with a reality dating show twist, full speed ahead.
if not then eh, give it a shot if you like but idk.
