It is a very beautiful Manhwa, at the beginnings the graphics did not convince me but the story is addictive and now I can say the graphics is really suitable, the plot is intricate and it is based on flashback and continuous alternance between past and present time. It talks about important thematic like the reception of homosexuality in the society and the reaction to other cultures, it treats about stalking, love, hate and pace, but not in a trivial way. I'm very pleased to recommend it.
