Are the scenes with Dream going to be similar to the one in the bathroom? Honestly, I didn't like the bathroom scene and the subsequent scene in the hallway (which I saw due to a bug), so if they are going to be similar to these I would prefer to know so I can rule her out.
Dream may want to help the MC, but there are a number of LIs with which I don't want to start a relationship.
For example, I have no interest in Charlotte. I didn't like the maledom bathroom scene at all. And I'm sure I would have liked the femdom scene even less. So it's best to ignore her.
Harem followers usually don't like having to choose between LIs, especially if they have to choose between LIs they like. For example, having to choose whether the MC has a sex scene with LI A or LI B is usually a bad idea, it's better to let the player choose whether they want the scene with A, or the scene with B, or both, or neither.
