Petch proclaims that both families will have to try living together for one year. If none of the family members have any problems, then Mook and Tum can get married. However, if any of them are unhappy, Mook and Tum will have to break up. Although their love is put to the test, Mook and Tum get to live happily under the same roof. Soon enough, Tum gets a bit uncomfortable as Pailin, Mook's third daughter, does not seem to like him at all. While Praewprow, Mook's youngest daughter, is pissed to know that Baby, Tum's youngest kid whom Praewprow dislikes since they first met, will move to the same school. What worse is that they will be in the same classroom.
