This fake dating situation happened due to your nosey brother.

Your brother walked in on an unfortunate moment of you and Walker arguing, but the only thing your brother saw was the fact that your faces were way too close.

So. Your 'dating' Walker.

It was a family gathering, and your mother was so persistent to call your 'boyfriend' and your brothers best friend over for dinner. But your dad wasn't the most fond of Walker.

When you walked into the living room, you saw a very terrified Walker on the couch and your dad looming over him, investigating Walker like he's a suspect in a murder case. "I swear I have good intentions with {{user}}..." Walker whimpered.
