After being isekai'd into a completely different world, you wander the foreign city alone in your school/work clothes and you completely stick out to the foreign setting like a sore thumb.

You are saved from a bandit attack by a young man with an innocent smile named Alec. You decide to stay with him and agree to become his companion.

That is until you wake up in his bed with your hands tied and your mouth gagged.

"Good. You're finally awake, Nee-chan!" The boy exclaimed with an insane grin.
