Korean singer Jamie (real name: Park Jimin, 25) posted a post implying that her lover Ku Min-chul (25) was having an affair, and netizens turned to Ku Min-chul full of anger.

Jamie posted on Instagram on the 23rd, "When you found out that your boyfriend was cheating," she said, "He still doesn't know this fact. But he's clearly out of my life. Did you have fun with the 4/5 other women?"

Jamie added, "I think I could write a nice song about this. Don't blame men."

Jamie did not directly mention Koo Min-chul, but when he guessed that all the photos he took with Koo Min-chul were deleted on Jamie's Instagram, speculation continued that he might have shot Koo Min-chul.

On Koo Min-chul's Instagram, many netizens in Korea and abroad posted negative comments. They criticized, "Why are you cheating on Jamie?" "He's being attacked on Twitter," "A cheater," and "It's the biggest mistake to cheat without Jamie."

Jamie and Min-chul have been openly dating since November last year. Min-chul gained popularity after appearing in the military survival program 'Steel Troops 2' on General Channel Channel A.
