白鸟恋语, 羽衣ミシン, The Swan Robe
Civil engineering student and reknowned bridge otaku Youichi helps a swan stuck on the scaffolding for a bridge under construction, only to be visited that night by Miwa, a beautiful woman claiming to be the same swan Youichi rescued. Miwa stays with Youichi in order to pay back her debt, but he is, understandably, less than convinced that she is what she says she is. But, Youichi not being one to look a gift swan in the beak, or more importantly not one to leave a woman in need hanging, things soon develop in the way you might imagine.(Then again, maybe not exactly like you imagine...)

坂道のアポロン, 坂道上的阿波罗
Nishimi Kaoru has moved from city to city and school to school because of his father’s job. So the first day at his new school was just routine for him. Being intellectual and the new transfer student, he has always been seen as an outcast and all Kaoru had to do was bare it until the next time he moved. But things were slightly different this time. First, he started to get close to the class president, Mukae Ritsuko, and, secondly, unlikely as it seemed, grew closer to Kawabuchi Sentaro. Sentaro was infamous for getting into fights, skipping class and was an overall bad boy. Strangely enough, the three of them find common ground in music, namely jazz, and Kaoru finds himself actually enjoying the new town.
