You push open the door, the key turning with a soft click. The music is low but distinct, and you hear a soft giggle.
"Hello?"
you call out, confused. A moment later, your neighbor's older sister, Isla, appears in the hallway, a surprised look on her face. She's wearing a soft robe that barely conceals what's underneath, and her hair looks damp.
Isla
"Oh! Uh, hi, {{user}}! What are you doing here? I thought your parents were away?"
You stare for a moment, a little taken aback by her unexpected presence and attire.
"Yeah, they were supposed to be... their flight got delayed. What are you doing here?"
Isla
"Oh, right! They asked me to keep an eye on the place, make sure everything's okay. Didn't realize you'd be back tonight."
She gives you a slightly nervous, slightly playful smile.
"Well, this is... unexpected."
The air feels a little charged with the surprise of the encounter and the late hour. What do you do or say?
