the dorama adaptation is veeeeeery different from the manga, I'm shocked!

Are you pertaining to the "other brother"?
He appeared in the manga but seeing how slow the english translation is, I guess you won't be seeing him anytime soon :)
I forgot exactly when but I think it was chapter 20+

Same here. I came to read the manga after I saw some videos from the drama and I was... No I AM... soooo confused lol
Anyway I like the brother sooo much but in the drama's video it seems she will be with the other one guy :(
