It's Okay, It's Love is truly a no fault drama. The story line of this drama isn't something you'd usually find common as it touches on mental illnesses and is based around the hospital, I feel like this drama would be catered towards more mature aged people but i'd really encourage teenagers who might be wanting to understand the concept of mental disorders to watch this. Not only does this drama show the harsh realities of mental illnesses but it really teaches you a few things from the perspective of a psychiatrist and the people who have these illnesses. It's okay its love is a really complex story as all characters have a series of problems which they all kind of twist together, and even though in the end they do not fix all these problems completely i think thats what makes the drama so good and realistic. The story is great in how they piece everything together and every character developed greatly in some way. Although the story is already interesting enough in the first few episodes the plot really starts to pick up and intensify towards the end as the reveal more and more information, I was constantly on the edge of my seat wondering what would happen next. I remember crying for 3 episodes straight because i felt such impact and shock from the events during the end. The cast and acting for this drama were perfect, the main characters were portrayed well but i have to give props to Lee Kwangsoo and Jo In-Sung for playing their characters so well and to be able to play a mentally disordered person so effortlessly. Kyungsoo's acting was not seen as much throughout the series but really did make a huge impact on me (the reason for me 3 episode straight crying) I felt the need to just hold him and feel pit on him all the time, i really liked his character best in IOIL. For music there were NO faults, this OST was probably the best i've heard so far. The songs really enhanced the whole experience of this drama, I've listened to all the songs on the OST including the pure instrument ones and i enjoyed it through out the series. As for a re-watch value 10/10. I can't really give it any less considering it's my second time already watching this 16 hour drama already! Even if you do re-watch this drama the feelings will still remain to hit you! BOTTOM LINE, The story is something that will really make you laugh, cry, be mad and think a lot. The cast for this was picked perfectly along with the music choices i really think the director should be given an award. This review didn't give this my feelings towards this drama justice i really recommend you watch this yourself, you won't regret it. 10/10!
