Sexless (2016)

Wearing a one-piece red dress, Ha-na, a bisexual woman, walks down the cluttered staircase and shares an intimate moment with her female partner Doo-na, who is currently taking a shower. Doo-na usually harbors a disdain for men, but she is displeased with Ha-na. Min-seok tries to persuade her to give dating men a chance, but she just ignores him. One day, however, a drunken Doo-na makes a mistake with him.
