Dang! Where do I even start?? First of all gotta thank my friend for recommending this! What a manga! The art is Shoujo like but the story itself isn't close to a pure heart-ed one! All I gotta say is that the story is surprising to the last minute; some parts may be predictable but most parts just surprise you!If you're a shoujo genre fan beware!!!
This Manga turns from Shoujo to freaking vich in an instant!

Also don't try to swear/criticize the characters too much; they may have their dumb moments in this manga but it's because of what they go through (granted there are some moments in the manga that make you want to kill the character >:/ )
Of course there are a few nice characters that anyone could love ^^

If you're interested read into the plot or try a few chapters and see if it captures your interest
