According to reports, TaeTiSeo will make a cameo as the girl group that 33-year-old father Dae Soo (Kang Dong Won) is a fan of and becomes a guard for.

TaeTiSeo shared, "We are normally fans of Kang Dong Won so it is an honor for us to act with him through this good opportunity. Director Lee Jae Yong led us well so it has become a good memory. Through this movie, we hope that a lot of people share a brilliant life."

Song Hye Kyo and Kang Dong Won play a couple who become parents at the tender age of 17 and raise a child who has Progeria (HGPS), which causes rapid aging in children. Their son Ah Reum grows into a 16-year-old boy who looks to be in his 80s on the surface, but is surrounded with a lot of love from his parents who are still figuring out life.

'My Brilliant Life' is set to premiere on September 3!
