To all my fellow fangirls out there: There is always that one character that's irresistible. You want that character to yourself, whether or not they have a canon love interest. Sometimes you're aware right away, sometimes it's a process...
1. Denial
Huh, that character's very interesting and very attractive. And aww, my feels- NO. No. Nope nope nope! This isn't happening. You're not falling for yet another character. It's just wishful thinking, that's all. Just for the moment. By the time the day is out, you've completely forgotten about the cute/hot/feels-filled scene that drew you to that character, right?
2. Anger
Wrong. You're still thinking about Character X. They're so perfect, so relatable, so... UGH!!! Your standards rise to Everest-like heights. Why must they be so amazing?! Why did they have to ruin everything? Everything was fine until they came into your life!!! Well, time to practice for your future as a crazy cat person...
3. Bargaining
Perhaps if you haven't watched the show/movie/read the book/played the game, you wouldn't have to deal with this. It's a bit late for that, though. You know you can't be with Character X, but one can find ways. Dreams are simple enough. Sometimes you have to enter the dark abyss that is Tumblr and find a Character X x Reader, or even just an "Imagine your Favorite Character". Anything to try to be with them.
4. Depression
After all the reading and imagining, it hits you. They're still not real, so there's no way you can really be with them. Worst of all, you're likely never going to meet anyone like them. You're going to be alone for all eternity because no real person could ever measure up to them.
5. Acceptance
Okay, so you love Character X. It's no big deal. All of this has happened before with other characters, and you're still okay. It'll likely happen with more characters in the future. It doesn't mean your life is ruined, you're just in love with an amazing fictional character. It happens to the majority of fangirls. It's all going to be fine, just going dream about being with this character or any other of your favorites.
