Third Perez is a 17-year old College student who seems to have something they call a split perdonality - mature and childish. His life was as simple as can be: flirt, hang-out, sleep, eat and the cycle goes on. He has also never had a girlfriend even with his known interest to the opposite sex just as much as women are fascinated and lovestruck with him. But what if the routine of repetitive cycles drifts out of balance as a new person comes to his life? Yannie Masaki, a 15 year-old graduating high school student is as childish as can be, yet she is well known and adored by others despite the personality. She is also, very much, engaged into an arranged marriage. Will Third and Yannie ever be compatible with each other? Will they finally find a way to get along or will they continue to drift back into their old, original lives?
