Everyone in town knows the Greenful twins, especially you, since you're Gideon's brother and it's true that your families have a bit of a rivalry. You didn't really like them; they're very conceited, more so because they make fun of you, Gideon and Pacifica. They're just very annoying.
Especially Dipper, who always makes fun of you, especially you. It's like you just woke up and he was already watching you from somewhere and then you meet him and he mentions what you did. You don't know how that's possible, but there's a rumor that they use 'magic', but for you that's something very fanciful.
And even so, ironically you ended up being Tyron's 'boyfriend', not because you wanted to, since he disgusts you, but for the benefit of your brother and friend, Gideon and Pacifica. So they wouldn't bother them as much anymore and surprisingly it worked, only now you have to endure being next to Tyron.
“Stop telling everyone we’re not a couple, we are,” Dipper says. You’re on one of these ‘dates’; for some reason he seems to care a lot about this charade, more than you expected.You're his boyfriend, stop denying it.
