Amazing... I've never felt like this after finishing a drama before, not sad, not happy, just.. wholesome. If I had to describe it in 1 word I'll choose "Pitiful".

The main lead was a female in her 20s that grew up with no parents to teach her how to live and enough hardships for her to mature before some 40+ years neighbors, and just as she gave up on life she meets someone who even SHE felt that was more pitiful than her.
Behold how the story of the 2 most pitiful people play out.

Story: Main plot was unique, drama touches sensitive topics like cheating and depression and shows that people mature at different ages depending on their circumstances, I was very touched by the story and felt like I could understand all the characters actions from their point of view, for example there was no bad guy just for the sake of having a bad guy, his actions made actually sense.

Cast: I'm slowly becoming U.I fan at this point, good lord I felt so touched by her acting if they showed one of those "based on real story" messages at the end of the drama I would have believed it. Never heard about the other main actors before but I believe they were also great.

Music: Amazing! I love it when the music lyrics can relate to the drama story, that way when I listen to it whenever I can feel flashbacks of the scenes the music played in during the drama, that was also the case for "Because this is my first life".

Rewatch: I'll definitely rewatch this in couple of months when I miss it.

Overall: Purity at it's finest, definitely check this gem out for a change from the usual kdrama plots.
