SDMU-180 If a man and woman who don’t know each other spend the night tied together by a 30cm red string, will they get turned on and have sex for the first time? Season 2

Three groups of male and female university students meet for the first time as monitors for a “psychological survey.” All night long, tied with a 30cm red string, we will have them live a thrilling life together and see if they will fall in love with each other! Please take a look at how the two, who are not allowed to remove the red thread in the toilet, the bath, or the futon, gradually close the distance!
