Eugene Coli loveless headcanons!
Disclaimer: being loveless does not make people evil. Eugene being an asshat is unrelated to his lovelessness. He's aspec coded SEPERATELY.
Definition of loveless / alove: Anyone who doesn't experience, relate, or identify with the term love.
(We have not yet played Detective Beebo 2.0! If anything in there is disproven we did not know at the time of writing this.)
Now, onto the headcanons!
1 - He always thought people said "I love you" as a pleasantry, or as an excuse for their actions. It's an empty word that essential means nothing to him.
2 - He's very love repulsed, however he used the word often in his relationships to "gain an upper hand" or to get closer to adding that checkmark to his list.
3 - Nina stopped saying it to him overtime, as there was always a significant change in his mood. At least, it felt big to her. Less eye contact, he'd go a little quieter, smile a bit less if they were having a good time. It felt weird, but she knew he was happier that way. Even if it left a bit of a void where the word used to be.
4 - At the start of their romantic relationship, Marigold said it a little to make it feel less "Friendshipy" as both thought things were supposed to feel different after "Getting together" and all that jazz. Neither felt good about it, the word, and the new relationship stereotype they felt they had to emulate for the sake of their checkmarks. They both dropped it pretty early, Marigold didn't really care, Eugene was relieved.
5 - Whenever he said that he loved someone or something, it always felt mechanical, forced. Like each syllable had a thousand regrets about it. As if his mouth struggled with the very idea of uttering it. It was a word often used on the rare occasions their parents sent a letter. That word has no place in his mouth.
Eugene Coli sucks and is a terrible guy and we hate him. But, to us he's so very headcanonable as loveless.
Final thoughts: Due to not knowing himself, or his real wishes. He lived his life by an imaginary checklist. Gaining many responsibilities, only to fail them all. He has ruined lives. Maybe if he had known himself better, if he had actually gone after his real goals, none of this would've happened. Maybe, he could've been a loveless marine biologist living on the coast somewhere, but we'll never know..
