Kiss Blue

A conventional tale of “friendship becomes something more” when one friend secretly falls in love with his best friend who’s quite a womanizer. Things start to change when that friend knows that his friend likes him, and they find themselves feeling awkward with this discovery.

From eManga:
He doesn’t remember when it began, but it seems Tomosaka has been in love with Noda forever. The thing is, he can’t exactly confess his feelings because the two are best friends. And to protect the friendship, Tomosaka has to lock away his feelings deep inside him. From Keiko Kinoshita, the same person who gave us LITTLE CRYBABY and YOU AND HARUJION, comes a story that explores the boundaries between love and friendship. Lose yourself within the pages of KISS BLUE.
