Well the second is her childhood friend, Fuyuku Nura,the only son of a wealthy family ( just like sonoko's) he has photographic memory and is the best whit fighting with sharp things (a little like a ninja) and he have a crush on Namu and he knows all her secrets and he know that she's in love with his (adopted) brother who saved her from a fire at his request. He and his family take care of her when her mom is out of the country at championships (her mom is a mondial tennis player). His parents love Namu. He's one of the few who know about her allergic reaction at chemical substances and he's the only one (at first) who know about her fear. He needs to protect her but she feel the same way. I forgot something? oh yeah, he's handsome and all the girls love him and in one chapter Namu faces her fear to save him and by the way Namu is the same: all the boys like her and that's why the ex-popular girl hate her and Nura and her share a pendant What do you think?
