It was the last day of her 18-day holiday in the UK and she needed a place to stay for the night.
When a friend offered his hostel room, she was uncomfortable as they would have to share a bed.
But because she wanted to save money, she relented.
It turned out to be a decision the Singaporean would regret.
That night last December, her junior college friend of five years allegedly raped her.
Even though Nicole (not her real name) had filed a report with Singapore and UK police, she said neither has taken any action.
She said Singapore police have told her they are unable to act against the man because the incident did not happen here.
She is awaiting a response from the UK police.
Nicole said she travelled to the UK for a vacation with her boyfriend last December.
But on the last day of the trip, Nicole was on her own as her boyfriend left for a family trip.
So, she ended up bunking with her friend - believed to be a Singapore permanent resident studying in a UK university - in his hostel room.
"At first I told him I would sleep on the floor because there was only one bed in his room," she said.
"But he insisted that we share the bed, that I would sleep under the covers and he on top of it."
Nicole said the two chatted while lying in bed until she dozed off. But she was awakened when he allegedly started touching her below her waist area.
