Shuji Kiritani (Kazuya Kamenashi) is one of the most popular guys in his school.  He is pretending to care for all of his classmates, but deep down, is quiet and doesn't open up to others.  But for some reason, when his eccentric classmate Akira Kusano (Tomohisa Yamashita) is around, he can show his true self.

One day, a new girl from another school comes to Shuji's classroom.  Her name is Nobuko Kotani (Maki Horikita).  Nobuko=Nobuta.  From her gloomy looks, she begins to get harassed by the class bullies in no time.  The harassment was devastating.  Her lunch gets ruined, she gets a vase of flowers on her desk meaning she had died, and she even gets water splashed while she is in the toilet booth.  After knowing that the bullying is by Bando (Fumiko Mizuta), Shuji and Akira advise Nobuko to try to harmonize with others.  But Nobuko tells them that she has tried to do so in the past, but every time it turns out miserable.  Shuji tells Nobuko to have a more positive attitude, and he protects Nobuko from the harassment.  However, he feels that the bullying won't stop that easily.

Hearing about this, Akira comes up with the idea to make over Nobuko from her looks to her personality, so that she'd become one of the most popular girls in their school.  That way, there's no way the bullies can harass her.  And so Shuji and Akira's great make-over begins...   A Cinderella story which portrays the social life of Japanese teenagers.  Can this gloomy girl really become popular in her school?

就学于私立高中的桐谷修二（龟梨和也饰），外表清俊，性格温和，又善于照顾他人，在班里扮演着人气男生的角色。借宿于学校旁边豆腐店里的某公司经理的公子草野彰（山下智久饰），头脑天真，一直围着修二的身边转悠。很酷的修二，整天被草野彰叫着铁哥们儿，也就不由自主地渐渐地显现出他原本天真的一面。一天，修二的班上来了一名叫小谷信子（掘北真希饰）的转学生。是个灰暗、沉默、自卑、很难跟别人交往的女孩。这样的信子＝野猪，也正好成了班上「整人俱乐部」的绝好靶子。信子从家里带的便当被恶意弄翻，课桌上被放上扫墓用的花，在厕所里被人用凉水浇等。修二和彰知道幕后黑手是「整人俱乐部」的梢（水田芙美子饰）后，建议信子要掌握窍门，学会迎合他人来保护自己。
但信子讲述了小时候的经验，鼓起勇气反击，却遭到更悲惨下场的过去。修二斥责信子不努力争取的消极态度，同时又积极保护着信子。即使是这样，信子受虐待的状况并没有得到缓解。得知真相的彰，建议将信子树为全校的人气第一女生。那样，梢她们就不敢对信子动手了。于是由修二担当制作人，从性格到外表，对信子开始了一场彻头彻尾的大改造。而饱受虐待的信子能成为人气第一女生吗？本剧细腻地描写了当下高中生的日常生活及心理状态。是一部灰姑娘式的青春剧。
