Have never played an otome, but that's kinda me with visual novels. Right now I'm living with my parents and even though I play them on my laptop in my bedroom, I'll still immediately Alt+Tab if one of my parents barge into the room. Also, if anything spicy happens in the game I'll feel a bit self-conscious especially if I'm aware of people being inside the house. Honestly, even though I know they can't hear whats happening during the spicy scenes I will usually halve the volume during those scenes.
