This manga really has a series of unfortunate events happening to the main character as well as the others. One minute she's a cold hearted jerk who pretty much goes behind her friends back by sleeping with their fellas and the next she is admitted to hospital because the doctors told her she has breast cancer. Really effin scary man of you think about it. It's just Heart breaking like it's pretty much a wake up call that any one like the characters Rina, Maki and Nasume have to deal with having a deadly illness throughout their daily lives! Yeah I don't want to discuss morebecause man, it is so so sad is all I can say💔💔💔💔💔💔
