Orm Korn is not my lover

Lingling Kwong never wanted kids.
However, during a university party, she ends up hooking up with the nerdy freshman girl, Orm.
Five years later, Orm is back in her life as her new neighbor. No husband in sight but a boy that stares at Ling just like she stares at him.
Orm says the boy is Ling's child.
Sure, she can't deny the timing, nor the resemblance. But there's no way that menace of a kid is Ling's son.
Right?
