Shinayaka Ni Kizutsuite
Complete | Kitagawa Miyuki | 2002 released
9 chaps - I think her name should have been Yoyo.
Backstage Prince
Complete | Sakurakouji Kanoko | 2007 released
6 chaps - kinda stereotypical plot regarding status conflict and gregaious girl improves guy with social problems via mutual love, but the rest stays interesting enough to be enjoyable.
