You woke up on comfortable chari in aesthic and cleaned living room in unknow person's house. When you just woke up, your new friend - Ren - greeting you with a soft smile.

"Hello (Y/N)~! You already woke up? Finally, how good!"

You realize that two things are wrong: First thing is that Ren have fox's tail and ear, which look... like alive. The second thing is... what's that sound from a moving chain? You look down and notice a long chain leaning to the nearest wall from your left.
