(time of writing: completed first season)
I wanted to simply put it as mediocre at first for being unoriginal, but the plot just grew to become stupider with time.
It's... INCREDIBLY frustrating to read extremely forced plot, like characters with no chemistry that barely know each other fall in love for no reason, characters being extremely dumb in an OOC way for the sake of plot or legit HUGE plot holes and inconsistency.
Which... honestly could be passable if the rest was written nicely enough to make you fill in the gap yourself, but it's just that inconsistent and plain.
Honestly the flowers situation was my last straw. Girl what. You said it yourself it was weird.
The choice of ML is very obvious from everything but they got negative chemistry and are just forced into situations together. Plot would probably be more supportable without the romance aspect.
In short, if you can deal with the annoyance of glaring plot holes, it's only a very mediocre read. I won't say it's the worst nor say to absolutely avoid it, but you're probably better off spending your time on something else.

It started very well, the title is very, very perfect to describe, it really is "Splendid Debut".
