A flashback shows us that after the MC passed out from the threesome in Ch. 32, Geum-Hae teased Bora Ki about being a virgin and first asks if she’s even been with a guy before, but then asks if she’s been with a woman.

Geum-Hae then kisses her and tells her to call her “Unnie” from now on.

When the flashback ends, Geum-Hae is shocked and has no memory of that happening.

In the review chapter, the author talks about the relationships between Na-Yeon, Yeon-Ah and Soo-Yeon and the reasonings for lesbian sex in the series.

He shows off a diagram of his ideal harem relationship, which is for the girls to be involved with each other as well as the MC. This prompts Yeon-Ah to break the 4th wall, saying that Na-Yeon and Soo-Yeon need to have sex with each other.

So it’s just implied the girls have lesbian sex with each other whenever the MC isn’t around.
