I was hooked until episode 4 or 5. Then it went downhill each episode it went by.
It was a mess. All stories were insanely poorly written.
Some actors credited here as "main actors" are nothing but secondary... the 2nd love story was beyond terrible. One of then is a coward and the other is obsessed with non-consensual kissing. The main story could be okay... no... jesus it could've been pretty solid, but the writers only got the premise right... after that was a disaster.

The worst part of it all? The last two eps. Painfully boring and with nothing but a nonsense and cheesy lines.
Some plots don't connect... it was a hot mess.

Honestly i've watched it all because i love In Seo Guk, if it had any other ML i would've drop it.
The rating i am giving is too high... but the first eps were indeed very powerful and the main leads showed immense potential. I'm so sad it turned out to be like this... just wow. The writers really lost their minds on this one.
