A South Korean man discovered his Vietnamese wife had secretly worked as a sex worker and slept with over 600 clients after he contracted multiple sexually transmitted infections (STIs).
The 41-year-old man from Gyeonggi Province, identified only as Mr A, shared his experience on YouTube channel ‘ThuU B Family’ on 11 May, generating over 1.8 million views in just eight days.

Foreign Bride Matchmaking Leads to Shocking Discovery
Mr A decided to seek a foreign bride after ending a 12-year relationship. In September 2022, he approached a marriage brokerage agency where he was introduced to several Vietnamese women.

He selected a Vietnamese woman, known as Ms B, who was fluent in Korean. The pair met in Hai Phong, Vietnam, and quickly developed a relationship.
After their initial meeting, Mr A returned to Vietnam a month later and got engaged. They held a traditional Vietnamese wedding ceremony in December 2022.
The couple relocated to Korea in March 2023 and held another wedding ceremony in September before visiting Ms B’s hometown for their honeymoon.
Their relationship took a dramatic turn in October 2023 when Ms B complained of lower abdominal pain. A visit to a gynecology clinic resulted in Ms B being diagnosed with four STIs.
Mr A later tested positive for the same infections.
He noted that his wife had passed her medical screening before entering Korea, which raised his suspicions about her activities during their marriage.
Secret Double Life Involving 600 Clients Uncovered
In October 2024, Ms B asked to stay at a close friend’s house. Mr A agreed on the condition she remain contactable.
Ms B went silent for three days. Upon her return, she refused to hand over her phone and became defensive, even threatening self-harm when questioned.

Mr A later found out the “close friend” was one of Ms B’s former boyfriends whom she met at an entertainment bar where she worked. When asked about their relationship, she admitted, “He was a regular client.”
After conducting his own investigation, Mr A obtained a work roster from the entertainment establishment. He discovered his wife had been offering sex services six days a week from 2pm to 9pm since May 2024.
During this period, she reportedly met between 3 to 5 clients daily, totaling more than 600 men.
Ms B had told her husband she was attending language classes, getting skincare treatments, or doing part-time work during these times.
Mr A filed for divorce and sought compensation for emotional and financial damages. Ms B initially responded, “Please delete the false information. I’ll pay you back by continuing to work at the bar.”

Shortly after, she cut off all contact and disappeared.
“I can’t stay silent. If she’s still in Korea, there could be more victims,” Mr A said in his video.
He also claimed he had enrolled her in a language course at Konkuk University, but she allegedly spent her time at the school library “approaching Korean male students while pretending to be a foreign student.”
The incident has sparked intense discussions online, with many questioning the background checks performed by international matchmaking services in South Korea.
