It’s hard to believe that they have a 10-year age difference!

The filming of the 2019 Chuseok Idol Star Athletics Championships recently took place which was joined by idols such as Red Velvet, TWICE, IZ*ONE, AB6IX, and PENTAGON.

Among the many cute interactions that were spotted, that of Red Velvet’s Seulgi and IZ*ONE’s Jang Wonyoung drew particular attention.

Ahead of the pitching games, the two idols sat next to each other looking cute in their baseball uniforms.

And what made fans squeal was the way the “sunbae” of 10 years, Seulgi pointed her hand-held fan toward her “hoobae” after noticing that she looked hot.

According to the fans at the scene, the two idols were sweet and friendly with each other until the pitching games ended.

In response to the sweet “sunbae” and “hoobae” interaction, fans left comments such as “That’s so sweet to see“, “Wonyoung must have been nervous“, and “My favorite combination“.
