SEUNGKWAN of SEVENTEEN and Lee Young-ji, known as the idol world's representative 'frenemies,' engaged in a fierce battle over 'titles.'

On the 19th, Lee Young-ji appeared as a guest on SEUNGKWAN’s YouTube content 'VIVIDIVABIDIBOO' on the channel ‘117,’ showcasing their spicy 5-year friendship.

The hot topic of the day was undoubtedly the title ‘Oppa’ (a term used by females for older males). SEUNGKWAN naturally referred to himself as ‘Oppa’ to Young-ji, saying things like, “Oppa is telling you...” or “Oppa really hates that.” However, Young-ji couldn't hide her look of disgust every time she heard it. She jokingly complained, “He’s gaslighting me. He has finally started calling himself ‘Oppa’,” causing the set to erupt in laughter.

The reason SEUNGKWAN is so obsessed with being called ‘Oppa’ lies in his family background. He candidly admitted, “Growing up with two older sisters, I’ve never been called ‘Oppa’ in my life. So, it’s a fantasy of mine.”

But Young-ji’s reaction was cold. She quipped, “Knowing that it’s your fantasy makes me want to do it even less,” and teased him by calling his behavior “middle-aged man tantrums.” The two bickered over the title for a while, creating a tension reminiscent of real siblings.

Fans who watched the video commented, “SEUNGKWAN calling himself ‘Oppa’ is so annoying yet cute,” “Lee Young-ji’s iron wall is the best in the world,” and “If they stay together, they probably won’t stop fighting for even a second.”
