On the June 16 installment of 'Knowing Brothers', Lee Soo Geun accused Jang Do Yeon of dating, saying, "I think you're dating. You've gotten prettier," and the other cast members agreed, "You have the face of someone who's received love and is giving love." She responded, "The only love I'm receiving is from my parents."
She also revealed, "It was past midnight when I got a text. It was a text from Seo Jang Hoon telling me to contact him. It was a number I didn't know. I was in the middle of filming, but it seemed urgent so I texted him back. He told me he only needed to call me for a moment."
Jang Do Yeon continued, "I called him when the filming ended at around 1-2AM. He told me his acquaintance was running a bag business and wanted to give me a purse. It was the first time I received a bag from a man."
Meanwhile, Kim Young Chul was oddly serious the whole time and refused to laugh, leading the 'Knowing Brothers' to poke fun at him for a supposed crush on Jang Do Yeon.
