Yes,i'm 2 years late and after dropping it at episode 6,i finally finished it. I kinda understand the hype. BUT i'm in the low percentage of unpopular opinions. I thought this drama had a lot of flaws.
First of all,the plot had it's up and downs. I went from being interested to being bored in half a sec. The development of the story leaves much to be desired. And a lot of people cried but i had a poker face until the ending,i think i teared up a little but nothing more.
And second of all,my biggest problem was with some actors in particular. The english speaking scenes were horrible. They were so cringy that i almost wanted to die. I understand it was necessary but damn,everytime they switched languages it was like turning a good actor into a bad one. And the american cast was trash.
I loved everyone else tho. The supportive cast was excellent and the chemistry between the main leads was cute even if their relationship was 100% bipolar. The female main lead changing her mind and dragging everything was kinda annoying.
I mean,it's not a bad drama at all.I enjoyed most of it. The cinematography was breathtaking,one of the best ones out there. And the OST gave me chills. But y'know,those flaws were pretty strong.

Overall,do i think it's overrated/overhyped? Maybe? But everyone has their own preferences. And focusing on the good things,like i said,i enjoyed most of it. And you're probably gonna enjoy it too,just don't start this with high expectations. I think that was my mistake. A popular,hyped drama,doesn't always mean a perfect drama.
