“Goku shouldn’t trust Bulma, because she is going to use him so she can get the Dragon Ball then leave him behind.
She is also bossy towards Goku. If Goku went with her to travel and find the missing Dragon balls, she will be a pest and keep on talking, along the way.
Also what happens if they are sleeping, and Bulma is figuring out how to get the Dragon Ball off Goku then plan to run away, as soon as possible? For a fact Goku is better off by his self because when Bulma is around him, she always ask random questions and when she mentioned the word borrow, it really sound fishy because borrow is like when you use it also she is just using Goku as a shield, to protect her from any harm.
She is also obsessed with handsome boys and changing the plans that her and Goku agreed on, she also tried to get on Kinto’un but she fell down on the ground, because she is not pure of heart and she is so unkind for Goku he is kind and sweet. Also Goku had never experienced being lied to nor being used just for protection, especially how Goku never met a human before other than his Grandpa Gohan, sure if he had friends with Bulma but he’s just getting used just because Bulma wants a really cute boyfriend.
But Goku only went because he’s kindhearted, which all he will do is to fight enemies that are twice as enormous as him and it will also be sad and curious because Goku is different from the other people because he has a tail and no one have seen a kid with a tail before.
