Credit to NightMareina. This is every Undertale romance in a nutshell.

Hi. My name is Trinity Rose. I am the only human in the Underground right now, which means everyone loves me yet hates me for being a human at the same time. Everyone thinks I'm perfect and flawless. Because I am.(literally every OC ever. This, my friends, is why I give my OCs something called weaknesses and unlikable traits...). All except one person.
Sans.
Sans. Even though he is a chubby skeleton and is lazy and has no hair people still find him attractive. I was surprised when he proposed to me. We never even dated! But now we are married.
But now Chara is trying to possess me and kill me and Sans.
