Two childhood friends plan to swap wives to break the relationship by swapping wives. It feels like a beating when a relative of mine is fishing for squid with someone else's rod. I will give his wife a cake. Netri feels like trying to soak next to it. An unusual space where conflicting and complicated emotions intertwine. The wives are heartbroken in the exchange game set up by their husbands and are confused and drowned in the intercourse. Iku's crazy 4-day record.
