FNS-177 | We're in a rut right before our wedding... We tried a 30-day abstinence therapy to recapture the excitement of the past, and as a result, our pent-up sexual desires clashed. - Tsubasa Mai

A couple on the verge of marriage faces a crisis that threatens to break them up... Sexless relationship. The woman is troubled, while the man continues to ignore the problem. Mai, who is searching for a solution, is told by a colleague who has the same problem, "If you abstain from sex for a month, something amazing will happen," and she suggests it to her fiancé. Although she is angry at her fiancé for masturbating during the abstinence period, she tries her best to make the month of abstinence a success. 30 seconds left... 10 seconds... 3, 2, 1... From there, they begin having intense sex that surpasses anything they had ever done at the beginning of their relationship. Of course, it doesn't stop at just one time, and with each subsequent encounter, they venture into bolder sexual acts they have never done before. Along with resolving their sexless relationship, Mai discovers a new side of herself.
