The first time I watched this drama, I've got bored on the first episode so I stopped. However, due to quarantine, I re-browsed my Netflix list and tried re-watching it again. And indeed I'm glad I did coz the storyline is great, funny and heartbreaking at the same time. The first few episodes might really bore you, just as what it did to me, but please try to be patient as the story will really get you hooked until the end. I just wish that they've had put more scenes on the past story as I really love how well executed the characters are and the setting of that time is fascinating. The past story got me crying and heartbroken on the end but thankfully the present time balanced it out with a happy one. Another thing, coz of this drama, I fell in love with Yoo Ah-In, damn his portrayal with both of his characters here is really outstanding. This is why after finishing this drama I watched his other dramas. The other two leads did an amazing job as well.
