Kp1's activites

I remember reading it last year, it's a story about 2 korean couples, they meet each other by accident on vacation on a beach and both husbands bang their own wives in front of each other, then they find out they live nearby and each couple is attached to the other's spouse, so after some hide and seek drama they all confront and decide to share and live together briefly sharing spouses, then it turns into some sketchy illegal sex game where somehow they all become participants and they comic ends with them catching the game mastermind and bringing him down. I remember the whole plot but forgot the name of this series, can anyone please help me find it?
