What's going on with lesbian content?
Lesbian content will be a minor theme, entirely optional, and is only planned to occur in one threesome. If the player selects the options leading to this scene, the MC will be the one to suggest the idea to the 2 girls in question. They will also be reluctant at first and need some convincing to go through with it. These two girls will not form any kind of romantic relationship with each other, nor will they pursue further sexual relations with each other.
Assuming you are following all of the girls' routes, there will also be 1 unavoidable lesbian kiss. You're going to have to trust me on this one, though. The kiss has very little to do with the girls being interested in each other. This kiss will not lead to anything and as alluded to in the previous sentence, will not be initiated because the girls want to kiss each other. It's hard to explain without spoiling it, but you should understand once the scene happens.
