Back to the 90s

High school boy Kong lives with his parents who always argue over a girl named Som. One day, Kong calls the number he sees from his father's old pager out of curiousity, and then gets instantly transported from 2015 to 1995 when his parents were his age. He befriends his father and meets Som who caused the whole mess. Kong now needs to find a way to separate Som from his father and also to find a way back home.
