A couple on the verge of marriage faces a crisis... Sexless relationship. A troubled woman and a man who keeps making excuses. Mai, seeking a solution, hears from a colleague with the same problem that "abstaining for a month will lead to something amazing" and suggests it to her fiancé.

Angry at her fiancé for masturbating during abstinence, she still tries hard to complete the one-month challenge. With 30 seconds left... 10 seconds... 3, 2, 1... From that moment, intense sex far beyond their early dating days begins.
Of course one time isn't enough. As they repeat it, they start trying bolder acts they've never done before. While solving their sexless problem, Mai discovers a new side of herself.
