This is my first kdrama review ever, so please don't judge my words too harshly hehe.
Honestly, I thoroughly enjoyed the first half of this drama. The acting, the humor, the cast chemistry were good enough to entertain and made me not think about various plot holes and romcom cliches. I even LOLed at a couple of moments.

However, it kind of went downhill in the second half. The writing got lazy and the predictability of the plot was almost annoying; the FL seemed to have lost most of her personality. Most of the episodes seemed like a filler, and the major conflicts introduced in the second half just felt very artificial. I think the drama could have wrapped up sooner if it didn't try to get all serious towards the end and would have still been just as good, if not better.

Overall, unless you are a huge fan of romcom/romantic kdramas, my suggestion would be to skip it.
