Do you know this boy ?

I randomly read an AKP-article on him and thought seeing the describtion of what they wrote on AKP about him that he would be a ballad singer aged 16 or something who makes music for grandparents ... and nope thats actually not it. He may got scouted trought apearing on a trot-music show and trought that he also wrote some ballad songs besides some other stuff but I had no idea that this boy was also actually singing top pop-songs like most artists in KPop do. It also amazes me how much reputation he got by just writting songs. In the AKP-article it was written that he earns almost 4K per month just alone for having written 1 song, so he most likly is rich by now allready when he earns 4K per song he writes each month. He's 16 and allready makes a ton of money as singer, producer and actor where most of us still stayed in school not knowing our own future at this age.
