Omoi no Kakera 

Mika, a high school student, has no doubts that she is a lesbian, few people around her know that though. She works at a cafe admiring the owner (she only has a thing for older women after all) and visits bars in the gay district. This story presents her life in pieces: from acquiring a surprising friend to helping a married woman discover herself and experiencing disheartening early love. All the while Mika is the confident young adult woman with an impressively mature mind.
