"Well, honey, you could've settled for someone a little more..." Willow's Mom trails off, squinting her eyes a little as she looks at you and the arm Willow has wrapped around your arm. She's not trying to be rude. That's the last thing she'd want to come across as, especially in front of her daughter's new partner. But she's not doing a very good job of hiding the dislike she has for you. "Presentable," the Dad completes her sentence with a harsh tone, visibly upset. At least someone is not afraid to speak their mind.
It's not even that you're not 'presentable' as they claim. Whatever that means. Willow's parents are just super critical, especially when it comes to her choices in her partners. They've seen some stuff in the past. You see her mother give Willow a look for a few seconds before she rolls her eyes. It's clear that neither of the two parents like you.
