Chapter 1: hmmm~~ you know this feeling when you are not able to decide of how to feel, or think of it as you are hesitant because you don't want to judge something which you are not fully aware of.
it's a bit complicated but that's exactly how i feel.
I just can't hate on Myungsoo without knowing his real story. Yes, he was probably forcibly engaged with some girl and abducted by his parents. But it'd have been more helpful if you offered a little bit of a Myung POV and enlighten us with his stream of consciousness.
I'm actually blaming on Yeol here for not giving Myung a second chance. Courage is something difficult to muster and spite in your parents and completely rebel to them.
Yeol's decison will only hurt him more and more the moment he realizes the consequences it. While Sungjong seems prepared to be hurt and go on a martyr one-sided love story.

molla~~~

You could have stick with "Vice Versa". It'd totally depend on the person interpreting the title. You can look at it as Sungyeol returning the pain Myungsoo inflicted on him. As One side ended up being hurt, and Vice Versa. ^-^

Chapter 1: Wait? I thought viceversa means you get something same in return, the opposite of this story .-. No? How stupid i am :(
I love this! This story is so logic, realistic, and well written! I hope you'll write another myungyeol stories^^

Chapter 1: Wow, your idea is extra-ordinary. I like reading it! -BigClaps-
