I personally think LIFE is a really good Manga. Its about this Girl named Ayumu Shiiba and she's not the brightest student. But, lucky for her, she "was" friends with a another girl named Shii-chan. (well, thats what she called her in the story. I don't know her name) Shii-chans dream was to go to Nishidate High School. Later, Ayumu realizes she doesn't want to be apart from Shii-chan, Just because they'll most likely go to different high schools. So, She studys hard (using Shii-chan's notes; making it hard on Shii-chan to study for herself) and makes it into Nishidate without Shii-chan (who failed her test and let her grades slip because she didn't speak up for her notes back from Ayumu.) You'll sound realize Ayumu's really slow and doesn't get things fast enough. And thats what happened, She didn't get the clues that Shii-chan was failing until it was to later. And now Ayumu has lost her best friend and goes into high school alone; just to make worster friends.
When Ayumu gets to Nishidate, She means a preppy girl named Manami Anzai. Manami likes to be the center of attention and doesn't care as to how she does it. (Like, if she has to lie, blackmail, or really anything) Manami has a boyfriend; Katsumi Sako, who has a fetish for bondage and keeps a scrapbook of the girls he has raped. Sako breaks up with Manami for unknown reasons. Manami then, asks Ayumu to get them back to together. Ayumu tries to be the good friend and works to try and get them together again, only to come across this book, he molests her and makes her his slave. However, his evil plans for her are thwarted because he has an abusive father who beats him to ensure his future relationship with Manami (both of their fathers are rich CEO's of famous companies). Around large groups of people he acts polite and sweet; but when it suits him to show his real self, that self is manipulative and abusive. He stalksAyumu, tries to make her call him "Master" for blackmail purposes, and even completely tricks Ayumu's mother into thinking he is a nice person. (Ayumu's mother was worried she wasn't doing well in school got her a home teacher.) After, the first rape attack on Ayumu, Sako promised to get back with Manami for Ayumu.
Manami then, follows Sako to Ayumu's house for "study" (Eariler, that same day Manami's other friends told her that they saw Ayumu going into a house with Sako. And they stated that Ayumu was trying to steal Sako away from her. Manami didn't believe it, because she asked Ayumu to talk to Sako for her.) But, before going to Ayumu, Sako bought some flowers. And Manami though the flowers were for Ayumu. (Sako's never given Manami flowers.) So, then Manami's starts believing what her friends were saying about Ayumu; She then get the whole class (later the whole school) to start bullying Ayumu (At first Manami was bullying a other girl named Miki Hatori, who laters becomes friends with Ayumu.) Then, last Manami get the teachers to do nothing about the bullying going on in the class.
So, now Ayumu and Miki are stuck at the hands of Manami. Until they find proof, That Manami and Sako aren't the angel, They've got the school to believe.
