As  a person who doesn't usually enjoy daily life themed dramas, I must say that 'Because this is my first life' was the best 2017 drama for me so far.
The cliffhangers started from day 1 and this is one of the reasons to be so excited for this series. Waiting for the next episodes was really a pain.
What I found so special about this drama were the characters on the first place. Se Hee was such an unordinary person and even though I thought Ji Ho was kinda annoying in the beginning, I just couldn't help but love her as the time passed. Really enjoyed the script writer's work. Almost every episode had those lines, full of metaphors that really make you question your whole existance. I also loved the secondary couples and even though in most drama they're just a waste of time, here they were just as interesting as the main one.
What I found lacking was that there wasn't much of explanation about Se Hee's past, which played a quite a big role this drama. On the other hand I think they could make the ending episodes a little more dramatic and emotional.
Overall if you are looking for something light-hearted, funny and with some good acting, this is perfect for you!
Hope this was helpful and sorry for the mistakes <3
