Just trust me and watch the Kdrama. It hits everything just right. Especially the feels. I never loved two leads more than I love the FL and ML of this drama. They were so so good and the the daughter too. Oh man The couple goals, the suspense, the family goals, the investigation and the thrills eveything keeps you completely engaged and you end up bingewatching like I did despite having exams in a month. Gonna have to take a break from watching such entertaining Kdramas.
All the characters are well thought and well acted and have depth.
Don't read any spoilers and just dive in for an amazing ride.
Except for a little of Ep 13 I loved each and every episode. Ep 13 is the only one which annoyed me a little especially on the FL's part but she is under a lot of stress so It's alright.
It's a Happy ending so don't worry about that.
