Oh My Girl’s Mimi reveals ex-boyfriend cheated on her after just 50 days of dating

Oh My Girl’s Mimi has opened up about her past relationship, revealing that her breakup with her ex-boyfriend was caused by infidelity.

On December 18, episode 8 of 'Sixth Sense: City Tour 2' aired on tvN, featuring the so-called “Mungtukz” cast members Yoo Jae Suk, Ji Suk Jin, Go Kyung Pyo, and Mimi, who were joined by guests Heo Kyung Hwan and Ryu Hye Young. Together, they traveled to Gangneung to track down a fake hot place.

During the episode, Mimi mentioned that she had never really dated before. In response, Heo Kyung Hwan asked, “You’re not a lifelong single, right?” While others tried to brush it off by saying she was an idol, Mimi firmly replied, “No, I really didn’t have one,” insisting that she was genuinely a lifelong single.

When Heo Kyung Hwan pressed further, asking if she must have dated at some point, Mimi confessed, “The last time was in high school, and it lasted 50 days.” Yoo Jae Suk then asked why the relationship ended so quickly, prompting Mimi to reveal the shocking reason behind the breakup, saying, “He cheated.” She explained that her ex-boyfriend was simultaneously seeing another girl.

As Ji Suk Jin reacted angrily, calling the ex a bad person, Mimi added her own harsh words, venting her frustration. Yoo Jae Suk jokingly pointed out that Mimi, who often struggles with pronunciation, suddenly spoke very clearly when it came to swearing, remarking, “Your pronunciation is good.”
