(On Hiatus) Shiroi Tenshi is not your average 17 year old guy. He's shy, quiet, a bookworm, and kind of awkward. His father hung himself a few days after he was born so his mother and a nice maid have been raising him. One day, his mom gets into a terrible car accident and dies in the hospital. The kind maid sends him off to live with his aunt and uncle since he has no place else to go. Turns out that his cousin is the cheerful Mako Mankanshou and her mother and father are his aunt and uncle. Suddenly one day, Mako brings home Ryuko Matoi, the new exchange student who has no where to go. The Mankanshou family happily take her in but Shiroi has his doubts if they should. The second they see each other, a spark strikes between them. Shiroi starts to feel weird around Ryuko, shyer and bashful and tries to avoid her but runs into her all the time. What will happen between Shiroi and Ryuko? What will happen when Shiroi finds a shocking discovery about himself and his family?
