Perhaps there are more lesbian scenes on Kate route. I don't know because I didn't pursuit her.
If you aren't on her path, the only real "lesbian scene" you have is that kiss between Flora and Isabelle. And you can even miss it, depending of your choices.
There also dialog where Flora seem to find Jacqueline (the art teacher) attractive. But nothing happen so far.
Also Jacqueline seem to be open to have relations with other women. But again, we don't see any lesbian action with her.
Finally, there is a lesbian scene between Flora and Maya, but it's a fantasy from the MC during a RPG game with the two girls, where he is the game master.
And I won't be surprised if depending of your choices, you won't see any of this.
So, the lesbian tag will really misleading players who like lesbian games.
Well at least, I can speak for myself, because my favorite games genre is lesbian protagonist games. I can still enjoy other kind of game, like this one.
But I would have been very disappointed if I have decided to play it because it had the lesbian tag.
