♡ Her real name is Yoo Seungyeon, but she's currently under the name of Gong Seungyeon.

♡ She was a rather well known trainee among the netizens.

♡ She's been a SM trainee for eight-nine years since around 2003, training besides Seulgi & Irene (Red Velvet), Kai (EXO), Henry (Super Junior-M), Krystal & Sulli (f(x)), Jino (former SM trainee), etc.

♡ She won SM's Best Face award in 2005, which led her to her casting.

♡ She was in the final lineup for f(x), but there was a last minute change and she was switched out. She stayed a little longer until she was one of the stronger runner ups for Red Velvet, but she didn't make it into the final lineup.

♡ She left SM afterwards and now she's under Yuko Company as an actress.

♡ She is one of three girls. The youngest is Yoo Jungyeon, a member of TWICE in JYP.
