What role does a boy of medium height fit for cos?

Well, what I want to say is that COS is not about whether you are suitable or not, but whether you like it or not. Well, if you really like it, nothing is a problem. After all, there is a strong post-production and photography. Of course it has something to do with yourself. Know the role before you go out. You ask, even if I recommend a role and you don't know it at all, is it useful? See what role you like. I hope this helps.
