His name is "Ju".
This is his online name. There is nothing in the information, it's blank! According to my experience, he must be a handsome guy. (Remember, this is a trick to identify handsome guys, yes~)
The facts tell me that it is indeed the case!
You ask me how I know? Because I know him, is it possible not to know someone if one is forced to stare at the back of another person's head every day? Impossible! So, I know him!
