The Friendly Loved Boy/Girl

The Friendly Loved Boy or Adorkable Boys is a stock character in most TV shows or movies or video games of the opposite version of The Mean Popular Girls and The Mean Popular Boy that not all boys or male characters were strong and attractive by everyone, but also rather be friendly and smart like normal students and people would do. They're often portrayed as male characters who are unpopular among the school and everywhere but are often friendly and smart to less popular boys. He is usually not that attractive and some of them don't have a sidekick. They may be unpopular and they treated them like hell because they're too weak, cryers or powerless, but the fans (of the shows, movies and video games) and the characters (e.g Family members, best friends and love interest/crush) loved them.
