Hey guys, isn't it a little weird to have your own characters flirting with each other?

Didn't look like flirting to me.  

But then, how would any romances ever come to be in any stories if the author didn't have their own characters interact?

Prince, characters in Fire Emblem talk sincerely to one another all the time, even in C-supports.
