Gender-Bender Love Triangle

Haruki, Kuuta, and Chiaki are childhood friends. Haruki tells Kuuta one day he's going to confess his feelings to Chiaki, and Kuuta tells him he'll back him up… Until Haruki wakes up the next day as a woman! He, rather she, is suffering from Feminization Syndrome and now has a huge rack and ass. Then one day, Kuuta asks out Haruki, who askes out Chiaki, who asks out Kuuta. Time for them to prove their love as a throuple!
