For Ep 1-5 it's an 8.5/10. Great fun through Ep 4, then treat Ep 5 as a fluffy epilogue and stop at 38min. After Ep 5 it slides quickly into very poorly written, clichéd, repetative, annoying, plot-predictable, and eye-rolling ridiculousness with unnecessary melodrama (with unbelievable and poorly choreographed fight scenes).

Ep 1-5: I was hooked within 20 mins. The premise was unique and the story was fun and interesting with relatable lead characters. There was great romantic tension and sweetness. Overall it was lighthearted and enjoyable. I eagerly looked forward to new episodes every week.

Ep 6-8 were a 3.5/10. I stopped looking forward to it and there was so much cringworthyness that I fast-forwarded more and more. I found the ending so cheesy that it wasn't satisfying.

After Ep 5 Kenji becomes the main antagonist. The actor playing Kenji is sooooo bad it makes any scene and plotline involving him lose steam and all seriousness. His over-active jaw movements make me cringe and laugh out loud at the same time. The part isn't written well to begin with, but the terrible, overly dramatic yet flat and shallow acting makes him the weakest link by a long shot and he dumbs everything down.

Some of the transitions between scenes are abrupt and the music is generic.

I can see myself rewatching Ep 1-5 at some point but I will never again force myself through Ep 6-8.

g_jun's review on MDL also sums everything up really well.
