Actress Go Eun Ah was on set to film the next episode of SBS 'Strong Heart' with her brother, MBLAQ member Mir.

The two showcased an extremely close brother-sister relationship on set, but Mir seemed to have a problem with his sister being too overly protective.

Mir remarked, "I feel like my sister always has me in the palm of her hand. Where ever I go, I feel like she's keeping close watch." Go Eun Ah who was a bit taken back by his remark came to her own defense saying, "It's because I care about my little brother so much. I am constantly worried about his well being."

Then she added, "I'm worried about him meeting girls, and I always look up girls that I think he may be interested in."

Mir hilariously continued to express his frustration over his sister who is overly involved in his life.

Meanwhile, the 'couple' special of 'Strong Heart' also guest-starred Hur Cham & Jang So Nyeo, Seo Jun Young & Bora, Kim Min Hee & Ahn Jung Hoon, Goo Eunae & Kang Seung Hyun, and more.
