His life changes when he meets Chung-Chung (Gigi Leung), a young woman whom he declares is very ugly.
In a fit of rage, Fumito orders his henchman Mark (Charles Shen) to kill Sing.
He is harassed and assaulted by the students, culminating in Sing being "crucified" on the front gate of the school with his (low-cost) garden hose genitalia hanging out.
Chung-Chung also works at the school, but has matured and is no longer the awkward, unattractive girl that Sing knew.
That evening, in a fit of despair, Sing attempts suicide but is stopped when Chang delivers a new microchip he's been working on.
To everyone's surprise, Sing returns as a powerful old lady, resembling a Park'n Shop mascot, in a bulletproof robe.
Ultimately, Sing transforms into a microwave oven and traps Mark inside, burning him to death.
