I really like it. It reminds me Cheese in the trap, the main character analize others behavior and think a lot about others personality. I really like psychological stories. Also the love interest seem so kind but with deep thoughts. My thoughts about John aren't clears yet. I can't trust him yet. He is so kind and good to be true.
I also like Saemin's personality. This author is really good with the story of the characters, is deep. I love it.
I almost cried the last chapter. This manga is perfect
