MITIGATION
Ms Teoh, the defence lawyer, sought no more than 32 months' jail for Fang, whom she said apologised to the victim, her family and those who looked up to him.
She said Fang had only intended to support the victim as he had a "natural tendency" to help those around him.
Ms Teoh disagreed with the prosecution's argument that there was a high degree of exploitation in his case, as court documents did not state that Fang had pressured the victim and there was no coercion involved.
Judge Tham, noting Fang's age at the time of the offences, said he had known what he was doing and what was likely to happen each time he visited the victim.
It was not a one-off incident where Fang acted on the spur of the moment, Judge Tham said. Instead, Fang had "taken advantage" of the victim's naivety and emotional vulnerability, he said.
The judge added that Fang's attempt to "gaslight the victim" for the sole purpose of "saving his own neck" was egregious.
Fang had not cared for the victim's welfare and had breached the investigation officer's instructions not to contact the victim, the judge said.
He allowed Fang to defer his jail term to Jun 16 to settle his personal affairs after increasing his bail by S$10,000 (US$7,700).
