Victim now has difficulty trusting others
Emotional scars have already emerged.
A psychiatrist who examined the victim, who is now 18, said she has been "feeling sad, irritable and angry" after the rape.
Her victim impact statement was disclosed in court and stated that she felt inferior.
The victim also has difficulty trusting and confiding in others as her mother, who is the person closest to her, did not believe her when she initially revealed what had happened.
Deputy Public Prosecutor Ramesh Ethan Ananda said: "The accused should have showered love and care on the victim... He chose to violate her sexually in her home and caused her irreparable emotional harm."
In a letter to Justice Woo Bih Li, the man said: "I hope that a chance will be given to me to undo the damage and to pay my penance for what I had done."
