Who’s the Guy Who Cheated on Seol In-ah? Shin Dong-yup Shares Powerful Advice: “It’s Not Your Fault”

On May 12, the YouTube channel Zzanbro Shin Dong Yup uploaded a video titled “Jung Kyung Ho, Seol In Ah, Cha Hak Yeon {Zzanbro} EP. 92 No Conversation in This Episode, Just Jung Kyung-ho LOL (He Was in His Own World).”

During the episode, while discussing how Jung Kyung-ho is a great confidant for Seol In-ah and Cha Hak-yeon, Jung Kyung-ho shifted the topic to Shin Dong-yup, asking Jung Ho-chul, “Don’t you get a lot of life advice from (Shin Dong-yup)?”
Jung Ho-chul replied, “Absolutely. He gives really great advice.” He then brought up Seol In-ah’s past revelation on tvN’s Life Bar, where she confessed that an ex-boyfriend had cheated on her, asking, “Did (Shin Dong-yup) give you any specific advice about that?”

Shin Dong-yup responded, “That was back when you were in college, right? When you were young.” Seol In-ah said, “About the cheating, I think like this now: ‘Maybe I did something wrong.’ I just try to move on coolly.” Shin Dong-yup firmly disagreed, stating, “I’m clear on this. Thinking ‘I must have done something wrong’ when someone cheats is absolutely the wrong mindset. You just need to realize how pathetic and weird that person is.” Seol In-ah nodded, visibly agreeing with his perspective.
Seol In-ah is starring in Oh My Ghost Clients, which premiered on MBC in May 2025. She’s been active in promotions, including press conferences and variety shows like Zzanbro. Her Instagram posts (@_seorina) feature behind-the-scenes content, earning praise for her chemistry with co-stars.
