After hardly searched in some forums, finally I got JHYO profile from allkpop's forum. Read my prior-related post here.

1. He is 1992 line. He is same age friend with Seunghyun and Minhwan.

2. He went to Seoul School of Performing Arts (SOPA). He was schoolmate of Seunghyun and Minhwan (and Kwon Kwangjin); Juniel's sunbae in school; and Lee Jaejin and Lee Jonghyun's hoobae in school. Well, FNC artists almost all went to SOPA, except their elders (Yonghwa, Jonghoon, Hongki, Wonbin). Idk about AOA.

3. His blood type is AB. Maybe he was the hoobae that Hongki talked about in Radio Star (2010, guest stars: Hongki, Yonghwa, JoKwon, Lee Changmin). Remember? The hoobae that has same personality with Lee Hongki that never greeted him properly. Of course, because he's AB!!!

4. His skill is playing guitar. Okay, he got it when he was a trainee in FNC.

Okay, those facts above strengthen my assumption in prior post. J-HYO was FNC TRAINEE.

1. Seunghyun support his debut and mention about they were trained together.

2. He is a followers of @FtDrMH1111, @chungxuan, @junielism, and @skullhong

P.S OMG!!! He comes from Busan, went to SOPA, and plays guitar. I wonder if he close to my hubby, Lee Jonghyun.

ENOUGH TO KNOW THE TRUTH!!!
