Albedo: Erma Felna EDF: Surprisingly subverted between Erma and Alfon, despite Erma only knew about Alfon via Toki, other than both being from the same homeland and having hot sex on the beach on the planet Ish-tako for one night, causing Erma to become pregnant with his baby, partly because Alfon was a much better option for Erma than Tavas after they decide to become a couple, even if Erma had very personal reasons for not hooking up with another man after her experience with Tavas, and partly because Alfon's death traumatized Erma a lot. It helps a lot that Alfon already knew Erma previously, but he decided not doing anything because Erma was dating Tavas previously, according with Gallacci in a FAQ.
Black Moon Chronicles: Wis and Hellaynnea in a way that Crosses the Line Twice. To avenge her lover, Hellayna arranges Wis' girlfriend Feydriva to die in a vanishing village. After a short fight, they agree to become lovers and they remain together for the rest of the series while Fey is quickly forgotten.
Blacksad: In "Red Soul", Blacksad meets Alma a few times, has sex with her once and then is suddenly so in love with her that he plans to run away with her.
Grandville: LeBrock and his first Love Interest Sarah. He barely knew her and only spent one night with her, yet her murder sends him into a Heroic BSoD and he briefly continues carrying a torch for her when he first meets Billie. It's pretty easy to forget Sarah even existed when his relationship with Billie becomes more serious.
Invincible: We're supposed to find Dupli-Kate and The Immortal's relationship to be wholesome, and also serve as a more responsible and "has-its-shit-together" counterpart to Mark and Eve's relationship, but we are never shown why the Immortal cares about her so much. Not only is she shown to be a serial cheater (granted, Rex kinda deserved it), she constantly makes disparaging comments about Eve's appearance and is shown to be a stereotypical nagging and manipulative Asian wife.
Marville: The opening recaps try to imply Mickey and Al are in love, but it never shows up in the actual comic. In fact, the prologue to #2 says they're in love, but that was never shown. Meanwhile, in #3, the prologue says they were never in love.
Marko and Alana of Saga are a great couple of characters in a stable relationship. It's downright bizarre that special agent Gale claims Marko was transferred to Alana's prison facility but within 12 hours she had helped him escape and they were on the run. Flashbacks nail down that there was zero chemistry when he called her to his cell (she hit him with her rifle butt to get him to stop yammering about conscientious objection). Shortly afterward she stole his translation rings out of lockup so she could read Heist's interracial romance novel to him. Sometime in the afternoon, he revealed that he was being transferred to another prison and she broke him out.
Antoine and Bunnie Rabbot were thrown together in one story with almost no build-up beyond the same issue they got together revealing that Antoine had once saved Bunnie's life. Thankfully, the relationship was well handled after that point, and it was easier to accept than most examples because neither of them had any romantic chemistry with other characters. The reboot kept them a couple but handled it differently by giving them a relationship built on mutual support and inspiration.
Worse off is the Echidna race — according to Word of God, echidnas have what is called "the Soultouch" — a sixth sense that also acts as a literal Red String for them and that once they've found their soul mate, they pretty much stay together, although there are some exceptions. This is why Knuckles and Julie-Su hooked up only after 24 issues and why he hasn't been broken up with her.
Spirou & Fantasio: The totally Ass Pull romance between Spirou and Miss Flanner, in the last pages of Aux sources du Z (Z's origins). The first is a confirmed Celibate Hero (to the point that Vito once chosen him for a mission due to his indifference to women), and only felt resentment towards Flanner until then. He was mad at her for apparently drowning Spip, and punched her, making it his only exception to his Wouldn't Hit a Girl policy. As for Miss Flanner, she'd been already involved for years in a Love Triangle with Champignac and Zorglub. She only showed condescension for Spirou as a result, certainly aware she was four times his age. It really hit them out of the blue, and many readers did not like Miss Flanner for reasons exposed in the Unintentionally Unsympathetic entry. Thus they really did not feel that this sarcastic, egocentric antagonist deserved to be this Ideal Hero's wife. Understandably, the next authors' run had suppressed the whole story (certainly through Time Travel) and Spirou is not even aware of Miss Flanner's existence since then.
