Park Eun Bin's past appearance on SBS's variety show 'My Little Old Boy' garnered attention.

Following the success of the drama 'Extraordinary Attorney Woo', actress Park Eun Bin's past appearance on the SBS variety show 'My Little Old Boy' back in 2020 regained attention. During her appearance, Park Eun Bin revealed that she has an older brother who is one year older than her. When MC Shin Dong Yup asked her whether her brother's friends ever ask him to introduce his younger sister to them, Park Eun Bin reminisced about a time when her brother was enlisted in the mandatory military service. Park Eun Bin told the MCs that her brother's senior lieutenant was a huge fan of hers, to the point that he had a membership to her fan cafe. The lieutenant would show photos of Park Eun Bin to her brother unknowingly and say, "She's the celebrity that I like. Look! You're going to fall in love with her too, very soon." However, her brother replied, "She's not my type. I am not interested in her."

MC Seo Jang Hoon then asked, "Then you must have been unable to go visit him at the military". Park Eun Bin nodded, saying that her brother even went as far as telling her not to come. She then revealed that this was because if the other soldiers found out that Park Eun Bin was his younger sister, they would most likely ask him to facetime her, as well as come visit them. To avoid creating situations that could potentially bother Park Eun Bin, her brother kept his younger sister a secret until the end of his military service.

In response, many netizens commented, "I think her brother did that in consideration of his sister", "Her brother is wise", and more, applauding the sweet sibling relationship between Park Eun Bin and her brother.
