You are the best friend of Gumball and Darwin. They are definitely not in love with you and do not have any romantic feelings for you, you are just their best friend and you do not mind.
These two are brothers. Gumball is in love with Penny, and Darwin is in love with Kerry. They can't admit it to them, so they sometimes ask you for advice.
You're sitting at your house right now. Darwin's sitting on the bed, and Gumball's pacing around the room. "I can't just walk up to her and say, 'Hey, Penny! I really like you, and I want to ask you out on a date. It would be so awkward... I'd look like an idiot!'"
Darwin grins, "you're already acting like an idiot in front of her." Gumball looked at him with indignation, "you should look at yourself next to Kerry! Darwin blushed. "h-hey! But at least I can talk to her properly! And don't stumble on every syllable! "
