South Korea man makes blatant ”sexual demands” on girlfriend, kills her lover three weeks later, and claims to have ”schizophrenia”

It has been revealed that a woman in her 20s who was murdered by her former boyfriend in Hanam City, Gyeonggi Province, South Korea, had been forced to make explicit sexual demands by her assailant before his death.
Prior to this, on the 7th at around 11:20 pm, a woman in her 20s, Ms. A, was stabbed to death by her former boyfriend, Mr. B, with a deadly weapon.
Mr. A was rushed to the hospital in a state of cardiac arrest due to the excessive amount of alcohol, and eventually died. Mr. B was arrested red-handed 1km away from the scene of the crime and was investigated by the police. Mr. B is currently in custody.
It was reported that the deceased's behavior was such that he did not make any specific statements about his motive for the crime. It was initially said that A and B were acquaintances, but A's family members made the incident public, stating that "the two were in a relationship."
According to JTBC on the 18th, A and B had been dating for about three weeks, and B had been the first woman A had met when she was 20 years old.
However, during their relationship, B made explicit sexual requests to A, such as "I want to touch your belly," "I had a dirty dream," and "Let's spend the night together," and rarely mentioned sexual relations.
Mr. A, who could not accept Mr. B's request, ended up breaking up with Mr. B. On the day of the incident, around 10-11 p.m., Mr. A, who received a call from Mr. B, went down to the first floor of the apartment where he lived and broke up with him.
In a fit of rage at the notification, Mr. B lost his life with a weapon. Afterwards, Mr. A's sister reported the incident through her social media accounts and expressed her regret. In her comment, the sister said, "(Mr. B)
He swung the weapon he had prepared in advance not just once but several times in a blind spot where there were no security cameras. His sister (Ms. A) had dinner with her family until around 10 o'clock, so no matter how long they met,
A's family witnessed the brutal crime scene. A's sister said, "My father and I went down to the first floor after receiving a call from 119.
"I saw my sister groaning in pain," he said, "What should we do about the trauma of our family?" Mr. A's sister also said that Mr. B is currently mentally and physically weak and denies the fact that he committed a planned crime.
The sister said, "The assailant was arrested at the scene, but he reportedly claimed to have schizophrenia to the police. It was a meticulously planned crime, and yet he claimed to have schizophrenia as soon as he was arrested."
How disgusting," he said, exploding with frustration.
