SDMU-180 A Man and Woman Who Don't Know Each Other Are Tied Together With 12 Inches of Red String and Have to Spend the Night Together...Will Sparks Fly? Will They End Up Having Sex When They've Just Met? 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!
