They were, it seemed, passionately in love.
She had his name tattooed across her chest. He told a colleague that he loved her very much and would do anything for her.
But it ended in tragedy when their bodies were found in a Geylang hotel room on Feb 1.
She had several injuries on her body, including a fatal stab wound on her neck. His body was found hanging in the bathroom, a coroner's inquiry into their deaths was told yesterday.
A handwritten note found in his bag gave an insight into how their love had descended into murderous jealousy.
It told of a spurned lover who was so consumed by suspicion she was seeing other men that he made up a list to question her about them. He even threatened to cut off her fingers one by one.
At one point, he wrote: "I kill you. I know everything."
It was under these circumstances that Indian national Chinnasamy Baskar, 30, met Indonesian Ruli Widyawati, 28, at Hotel 81 Palace in Geylang on that fateful Sunday.
Investigation officer Senior Staff Sergeant Aliden Hamad told State Coroner Marvin Bay that based on the available evidence, he believed that Mr Chinnasamy, a construction worker, had killed Ms Ruli, a domestic worker, before hanging himself.
When the hotel manager checked on them that evening, Ms Ruli was covered in blood and lying motionless on the floor. She was facing upwards, with a towel placed over her body.
Mr Chinnasamy's body was found hanging above the toilet bowl.
Loose notes were scattered on the floor, smeared with blood. A kitchen knife with a 12cm blade was found at the scene.
The handwritten note was a sign of jealousy and relationship issues, Senior Staff Sgt Aliden said.
It is not clear when the couple met, but Mr Chinnasamy's direct supervisor found out about their relationship in August 2012.
Ms Ruli had texted him to tell Mr Chinnasamy to stop going to her employer's home to disturb her. It foreshadowed what was to come.
Her then-employer knew her to be married with two children in Indonesia, but also that she had a male Indian friend.
Ms Ruli even had Mr Chinnasamy's first name, Baskar, inked across her chest, Senior Staff Sgt Aliden said.
Money also figured prominently in their relationship. Mr Chinnasamy's colleague and roommate said he gave Ms Ruli money whenever she asked.
Last November, Mr Chinnasamy borrowed $200 from him to give to her.
When told that he should not give Ms Ruli so much money, Mr Chinnasamy said he loved her very much and would do anything for her.
