One of the biggest mysteries of Kdrama land is the rating of this trash drama. I literally barfed my entire lunch when I saw old dude kissing Krystal and playing as a universaty student bleaaaaah. I just wish I could unseen it an easy 1 for me. Could have gotten a new reply series instead of this trash. The prison Drama didn't move me as well it's was underwhelming like everything about this drama, there are plenty prison Dramas that tops this, I think if the reply series directors wasn't in it, it would have flopped. Anyway don't reccomend unless you want cliche drama that want to move you but does, an unwanted romance and edgy characters
