Can we see some of that brain rotting?
👉👈 you actually want to-
Main ship on the brain: Jasper x Catherine
Tragic couple(as Alice is destined to kill the Jabberwocky), but when they're together it's only them. They're the only people in the world. Small pink kitten standing in front of a giant jabberwocky to protect him. Also possible poly/open relationship with Jensen and Xander. Mainly that I can't see any of them being jealous of one another and 3/4 are already affectionate to each other (Jensen is the main tsundere). Mainly for cuddle pile aka how they slept together as kids, Catherine would cuddle Xander with Jasper to her back and Jensen to Xander's with their wings protecting all of them(and warmth cause forbidden forest). I can see them still doing it even at NRC.
Second couple: Ephraim x Lovette
Blind knight with a vain girl who "only cares about her appearance". Sacrifice meets selfishness. Lovette is so used to using her looks to get people to like her/do things for her but that won't work with Ephraim. Lovette refuses to lose stuff for others, while Ephraim lost his sight while protecting his sister. Lovette can't move from the past (still stuck on Ambrose's death) while Ephraim knows there is no use crying about what was, his sight did not define him. He is still himself without it(not to say he didn't go through his own grieving process). Even when Lovette tells him that she's pretty, he just chuckles and says "I'll take your word for it, Miss Sieglinde".
Last couple on the mind: Sai x Veil
Enemies to lovers? Somewhat. Veil is Veil after all. Sai is a very mischievous snake, loves to rile people up. Veil cannot emote (yet). So he will keep trying until he gets a reaction. Snake vs sea serpent. Veil is quick to hiss and put Sai in his place, while Sai just smiles as she does it (annoys her more). Sai has thrown water on her to see her merform which didn't work (Veil did not use a potion, she can take her "merform" aka serpent form whenever/wherever she wants)
