I think when it comes to them liking each other, Derek is more self-aware about his feelings for her. Casey definitely has feelings for him but seems less ~aware~ of them than he is. I think this would explain "same difference" because she truly just hasn't gotten to that point of being able to identify and acknowledge what she's feeling and might still think that the affection she feels for him is familial

I love how the fanbase collectively agrees that Derek was in love with Casey first. It's just common knowledge at this point; not even something to fight about.

Life with Derek was Cruel Intentions for Kids.

Paul Greebie always feels like he's 00.2 milliseconds away from looking at the camera like he's on the office.

Sometimes I watch bits of Life with Derek and I am just in awe of how much Derek loves Casey. Like Oh my Word.

I don’t think people have to ship Dasey, but if you don’t see their relationship as romantic, what do you think is happening between those two characters? Are y’all actually watching the show thinking they have such a wholesome sibling relationship? Like the eyesex is normal siblings behavior for you? Genuinely wondering.

"When two of your siblings are literally in love with each other; but you're still considered the black sheep of the family." - said by Edwin Venturi probably.

I don't ship Lizzie and Edwin but i do see them as mlm/wlw solidarity, also Edwin gives me he/they vibes.
