Aradia(hearts)Sollux: Jolie-laide (French)- "ugly-pretty"; a type of beauty who is not conventionally attractive, but has a sort of fascinatingly quirky/ unusual look that makes them even more charismatic
Sollux is not what you would consider conventionally attractive. His teeth are misaligned (an overbite that resulted in a word-obscuring lisp), his shoulders are too narrow, he is so thin as to look unhealthy, he has eyes that are an eerie shade of brown so light they are nearly yellow, matted hair that is clearly uncared for, and a tone of skin that spoke volumes about how often he saw the sun (hint: not at all). And his personality, from an entirely non-biased point of view, isn't much better.
So no, you think, your boyfriend is not conventionally attractive.
But the way his lisp softens his words and manually slows him down (he speaks fast and harsh, always so eager to speak his piece and be done, never anything less than blunt) is endearing. You love his voice. It's nasally and low pitched, and often his words come so fast it's like listening to a river burbling along. You could listen to him forever!
Plus the eyelashes that frame his oddly colored eyes are long, lush, and dark. They accentuate them, and you often joke that it makes him look supernatural. Like a mage, or something with an equal amount of magical prowess. (You mentioned that once out loud to him, and he laughed at you for a half hour straight!)
The complaint about the width of his shoulders you aren't even going to talk about (because wow…how rude is that, not to mention almost one thousand times more vain and shallow than the other "detracting features" mentioned). There is literally nothing wrong with Sollux's shoulders.
His weight though, that does concern you. Not for aesthetic reasons, because you rather like your boyfriend's distressed, grunge princess-type look. But you worry about his health. His metabolism is too fast for him to be forgetting meals (and he's always forgetting meals). Luckily he has you to pull him out of whatever funk he's fallen into lately, he'd likely never eat otherwise! He's always been way too invested in those projects of his (he just wasn't taking good care of himself, the dork).
His hair wasn't a large problem; you've already mentioned you rather enjoy the grunge princess aesthetic. And neither is the pallor of his skin! You really are dark enough for the both of you, so whatever and who cares!
About that overbite, aside from its noted and cherished contribution to his stupid, charming lisp, well…Let is be said that, well, it forced him to be an exceedingly innovative kisser. The things Sollux could do with his tongue –
"AA," Sollux deadpans, "You're staring."
"Sorry," you say, not at all sorry. "I love you, Sollux." And you kiss him, because thinking about all of his charms has left you craving his touch.
