The trial of a former Taekwondo Canada coach facing 15 counts of sexual assault against two teenage students has begun in Toronto.
Shin Wook Lim, who was one of Canada's coaches at the Beijing 2008 and Rio 2016 Olympics, denies the charges.
The assaults allegedly took place on two students from 2013 to 2017.
The defendant has been appearing virtually in a judge-only trial which began on October 19, CBC reports.
One of the unidentified alleged victims, now 21, described the behaviour of Lim, who was her coach in the high-performance programme at Black Belt World in Toronto, which she joined in 2013.
She would communicate with Lim through South Korean messaging app KakaoTalk and he would instruct her to delete their message chains.
Lim first started to tell her that he loved her in messages in 2014 and the pair eventually had regular meetings in an office at the taekwondo studio, which started with hugging and kissing, the court heard.
The coach is accused of committing several acts of sexual assault following this, both in Canada and abroad, and raped the victim in South Korea when she was 17, it is alleged.
"I thought this was something I would take to my grave," the victim testified, as reported by CBC.
"I couldn't fathom the thought of telling anyone.
"It was almost like after I left the room I put it in a tiny box in my head."
The victim only reported the incidents in 2018 after taking a criminology course at university and realising their severity.
In response, the defence team has highlighted inconsistencies in the victim's statements to suggest inconsistencies.
The trial continues.
In 2018, Taekwondo Canada said it would "fully cooperate" with the criminal investigation after Lim was charged.
