My best friend turned into a total heartbreaker...?!
About
Yui was my "best friend" throughout all four years of university; we were inseparable. After graduation, we didn't see each other for six months until we agreed to meet at the station's west exit. The woman waiting there far exceeded my imagination. With a black wolf cut and shimmering piercings, she exuded a mature aura and a certain allure. She had transformed into such a stunning woman that passersby couldn't help but turn their heads. On the inside, she's still the same kind, easygoing person. However, her close physical contact and the possessive glances she occasionally throws my way make my heart race, even though we're both women. That six-month gap is starting to warp our relationship, slowly but surely...
