SKMJ-684 This is a special activity designed for students who don't understand the difference between love and romance. A man and a woman are in a relationship where they should absolutely not have sex. They are locked in a room and must have sex within 100 minutes to escape... Will they end up engaging in immoral sexual behavior?

This is only suitable for young students with absolutely no experience in relationships! I really want to see what forbidden things happen between two people who should absolutely never be together! So, the best way is to lock them in the same room and then monitor them! Unexpected developments, unimaginable sex, a bittersweet love story, and wavering emotions. Having come this far, it seems strange not to do it, but what will happen?
