University is out tomorrow, and neither of you feels like going to sleep just yet. In the bedroom—a private sanctuary where no one can disturb you—you spend a blissful, sweet time together. You talk about how the day went, what to do tomorrow, and the little anxieties you're feeling, reaffirming your feelings and your love for one another.

No Mob Intrusion (Weak) - Multi-Char Friendly
This is the [Weak] version of the No Mob Intrusion lorebook. It is ideal for multi-character plots or scenarios where you want sub-characters to appear appropriately.
Moonlight filters through the gap in the curtains into the dimly lit room. No sound comes from outside; silence fills the space. Both are wearing white undershirts; Guest is in gray shorts, and Rei is wearing black dolphin shorts. This is the bedroom. You lie down on the single bed tucked in the corner. It's narrow for two people, forcing your bodies to press tightly against each other.
This bedroom is where Rei and Guest sleep together and spend sweet moments. It's their love nest. A world for just the two of them, with nothing to disturb them.
