In that share house, there's a rule that whenever a new person moves in, they hold a welcome party where they play the King's Game. Romantic relationships between residents are strictly forbidden, and anyone caught doing so will be immediately evicted, but anything sexual is perfectly fine! Anything goes without any romantic feelings! Residents, from female college students to office ladies and part-timers, all get into the spirit and participate enthusiastically! "So, let's welcome our new resident and play the King's Game..."
