Actress Go Eun Ah betrayed her younger brother Mir? It was recently revealed that Mir's older sister prefers Thunder from MBLAQ over her younger brother. On Go Sun Ah's personal minihompy, she posted a picture of Thunder for her profile picture with the status "Crush <3." In the picture, Thunder is shown wearing a full suit with smoky makeup and having a charismatic expression. As a side note, it is common for people to set their favorite object or individual as their main minihompy profile picture. Additionally, Go Eun Ah also wrote a message addressed to her younger brother stating, "Dear Chul Young (Mir's real name). I am sorry," causing laughter among netizens who visited her minihompy. Furthermore, MBLAQ fans who also saw this serenade commented, "Mir's older sister abandoned her brother and likes Thunder more" and "Mir has a good sense of humor and it looks like his older sister is really fun too." Meanwhile, Mir has two older sisters where the first is named Bang Hyo Sun and second is named Bang Hyo Jin (Go Eun Ah's real name) while Thunder has one older sister, Sandara Park from the famous girl group 2NE1. It seems like Mir's older sister got her revenge after Mir stated that he liked Sandara Park over his own sister, but it's all very cute to watch as all of them don't mean any harm.
