Yes it will be considered as UA.I have a question regarding this rule
{Any story having any Underage Character (below 18 years of age) will not be accepted and each story should follow the Story Section rules as well as the General Rules of the forum. That's why genres such as Gay or Bestiality will not be allowed.}
my question is what if in the story the main protagonist relates about his childhood days as that will be an important part of his life the way he toiled hard to reach where he was. will that be considered as UA?
In contests UA is not allowed not even as passing references.
I know you are an old member and you know very well that this rule is in implementation since the very first contest at xossip as well and what were the reasons behind it.
