The Angel, the Devil, and Me

Nozomi Shindou is house-sitting for her uncle for two weeks while he's on an international business trip, and though she knows she ought to let the neighbors know, she thinks it's too much trouble...until her neighbor happens to be utterly gorgeous. His name is Yuuta Honjou, and she's in love at first sight, until his roommate Chiaki Shiki steps out and is somehow even more gorgeous than Yuta. The possibility of a relationship between her gorgeous neighbors fuels her fujoshi mind (and her online novel), but she can't help but wonder...what is the actual relationship between the two? And is there any space in it for her?
