He is a member of B.A.P and his real name is Moon Jongup. We BABYZ (B.A.P fans) have this kind of joke about his name.

Jongup vs Jongyeup

Jongup for us means: soft, cute, adorable, shy, happy virus, fluffy, goofy around and it's good for soft stan

while

Jongyeup for us means: hot, y, snake, dangerous, devil, bicth, don't give a fck and so on. it's totally good for hard stan.

Jongup actually named his IG @moonjongyeup for real (do follow him). *Smirk*
