Boyfriend is cheerful and confident in his abilities as a rapper. He has shown to get nervous when he messes up a note, however, and seems to be mildly afraid of lightning, which the same could be said to his girlfriend relatedly.
Boyfriend is also so reckless and overconfident that he's essentially fearless.
What his relationship with the Girlfriend is exactly like is unknown, though it can be safely assumed they both dearly care for each other. This is shown when he catches her after Pico saves her from the Tankmen and he smiles as she hugs him. He then sings the rest of the rap battle against Tankman alongside Girlfriend.
It is also noted that Boyfriend, along with Girlfriend, does not like swearing. As when Tankman curses at the couple, the two are clearly uncomfortable and upset by his profanity.
Boyfriend's main goal in Friday Night Funkin' is to gain the approval of Girlfriend's parents so he can date her. However, he seems to hold some form of hostility towards them, most likely because of Daddy Dearest's attempts to either humiliate or sometimes murder him. As in a sketch, Boyfriend can be seen giving Daddy Dearest the finger. Another example is an unused animation of him angering the latter by hitting him with his microphone.
Despite his somewhat intense relationship with his Girlfriends' parents, Boyfriend seems willing to get along with them when they are nice and show decency to him. This is evidenced after he defeats Mommy Mearest in Week 4, she and her husband start to develop some form of respect towards him, as they invite Boyfriend to hand out candy at their house on Halloween.
