So, Momoko Isshiki suddenly wants to divorce his husband. Then, the guy finds her diary. Where she relates all her affairs and extra-marital adventures.
The husband gets rekt and he dismayed. Once he recovers himself, he finds out he has time-traveled 3 months back and he gets to relive all the wife infidelities. LOL. Time traveled solved.
And the good thing about this movie is that Momoko Isshiki bangs those guys like a savage. Nice stuff indeed.
