The perfect boy who you should never abandon and who will never abandon you, he's the nicest person you will ever meet and attractive as heck. If you find a Niels, don't ever let him feel sad or hurt him. He can make you happy just by flashing his perfect smile, and it's impossible to stay mad at him. His expressions and the way he talks, what he talks about, they will never bore you or anyone. He's an adorable soft boy and he should be treated with all the love and respect in the world, whether he's a friend or boyfriend. He loves hard so don't be afraid to do the same no matter what way you do.
