In the K-pop industry, celebrities and idols having stage names are not shocking. Several personalities changed their real names due to various reasons, including having a hard to pronounce the name, avoiding to overlap with a celebrity with the same name, due to fortune-telling or too ordinary to shine so they decided to change it.

Commonly, English stage name such as Red Velvet's Joy, MAMAMOO's Solar is accepted, as well as mononyms including EXO's Suho, BTS J-Hope, SEVENTEEN The8, not to mention stage names consisting of letters only such as BTS V and RM, INFINITE L, VIXX N, etc.

However, the following K-pop idols seem like they are using their real name as their idol's name, but they are actually not! See the list and you will surely be surprised to know that it is only their stage names!

1. ASTRO Cha Eunwoo

Are you aware that the "face genius" Cha Eunwoo is actually using a different name than his real name? Well, yes. He was actually born as Lee Dongmin, but after starring on a web drama, "To be Continued," wherein the fictional character looks like him, he started using it then.

The people around Dongmin got used to his character's name, and the idol also liked it, and that's why he became Cha Eunwoo then.

2. NCT Jung Jaehyun

Jung Jaehyun has the most different and unique story! Jung Jaehyun was actually his real name, initially. However, he legalized it into Jung Yuno, so basically, he's only using Jaehyun now as his stage name!

According to Yuno, his parents have three options for naming him. His father likes Jung Lin, his mother wants Jung Seonwoo, so they ended up naming him Jaehyun which is their third option. Also, according to a fan, he changed it because his grandmother wants to write his name using Chinese characters, but Jaehyun doesn't mean anything in Hanja.

3. Super Junior Yesung

Well, for those who don't know, yes, Yesung is only a stage name, but his real name is also confusing! When he debuted, fans and even him acknowledged his real name as Kim Jong Woon for a very long time. However, in 2016, he revealed that his mother actually legally changed it into Kim Jong Hoon after 30 years and he only learned about it three months after!

According to his mother, his name means "cloud" when written in Chinese characters but clouds cast a shadow so it doesn't sound good. However, fans and Yesung are still using Jongwoon or Jw.

4. BLACKPINK Lisa

Similar to Yesung, Lisa is only a stage name, but even her name Lalisa Manoban is initially not her real name. The BLACKPINK member was born as Pranpriya Manoban, but she legally changed it after consulting a fortune-teller.

5. Seo Kang Joon

Seo Kang Joon, a member of the former actor-idol group 5rprise is also using a different name from his real name! His birth name was Lee Seung Hwan, but because there's already a famous singer named Lee Seung Hwan, the agency completely changed his name into Seo Kang Joon.

7. Choi Sulli

The late Sulli was famous for her name Choi Sulli, but her birth name was actually Choi Jinri. Before debuting as a young actress and joining SM Entertainment, a reporter suggested changing her stage name, as Jinri sounded too "Christian" and other people with different religions might not like it.

Sulli reveals that her stage name actually means "pear flower in the snow."

8. Kim Chung Ha

Chung Ha is also not the idol's real name! Her birth name is really Kim Chan Mi. She has yet to legally change it, but she was hesitant that she might lose the real "Chan Mi" as well.

People are actually shocked to know that Chungha is not her real name, as she joined MNET's "Produce 101" as Chungha that became known to fans and idols.
