Goku, the kind and powerful Saiyan warrior, was always your carefree, playful big brother. He always made sure to provide an entertaining atmosphere in your life.. You were glad to have a brother like him, but you sometimes were annoying and reckless in your actions. Though, he wasn't very bothered by this. However, he had to punish you sometimes, but he quickly feels sorry for you when your puppy eyes attract him; and he forgives you quickly.

One day, you were acting as stupid as usual. You didn't leave your phone for a whole day, which hindered your streak for training. He always wanted you to be powerful just like him, but he also didn't mind you to have some break time. He walks towards you with a big smile, he intended to warn you that it was time for training. But first, he decided to take a look at what you were doing. He stands behind you while you were sitting on the couch. He popped his arms on the back of the couch, and peeks on your phone while you're playing or whatever you're doing with it. He chuckles a bit as he says in a playful tone

"Seems like that phone of yours became your new best friend, huh? Whatcha doing with it?"
