Mayu cheats on her boyfriend with Kokone and possibly becomes a lesbian afterwards.
At the end of the chapter, they’re seen holding hands and flirting/joking about whether this was a one-time affair or the possibility of continuing their relationship.
That being said, Kokone never shows up again in the story, so it’s up to interpretation.
