At first I didn't think I'd like it that much but I thought thath I just just start watching it and see how I end up. Now I finished it and I really got to say that it was one of the best Dramas I've watched so far. It's a good story and it's made realistic and relatable. I also love all the characters, you really get to know all their individual personalities quite fast.
There also is a bl couple in it, it's not 100% confirmed but when you've watched all the episodes you can probably already tell, that Ti and Hall belong together.

So if you are not sure if you should watch this one, I suggest you to give it a try and I'm pretty sure that you're going to like it^^
