“Bodkawee” (Krist Perawat), a 30 year old man leading his dismal life in a tiny rental room earns his living by being a subtitler.

While "Pearmai" (Aye Sarunchana), his first and one sided love for the past ten years, has been living a completely happy life. She is about to marry "Pisaeng" (Gawin Caskey), Bodkawee's hot and popular classmate. One day, “Bodkawee” discovers that a crystal ball music box he intended to give to "Pearmai" in his first year of university can transport him back to his 18th year. So, “Bodkawee” attempts to mend his relationship with "Pearmai," but "Pisaeng" is always present and interrupts him. Things take an unexpected turn when, instead of getting together with "Pearmai," he ends up getting closer to "Pisaeng." How will their love manifest itself now? Let’s stay tuned and find out together.
