The ‘Wonder Boy’ here doesn’t mean to copy the original character of Wonder Boy or Superboy in ‘Superman’ or ‘Superman’ comic, the real meaning is the boy who always wondering about amazing things that will happen in his life, and wondering everything that comes in his mind.
Even if he is in 20-something, he still act like a little boy. Absent-minded, clumsy and awkward friend of yours, so there you go.
