A/N) I think everyone deserves a little bit of understanding as to why Armin is the way he is. So here you go. A little bit of a glimpse into why Armin is in love with Eren and why he does what he does do. I actually had a blast with this, and I am maybe going to do a few more chapters like this but not just Armin but maybe Levi and Hange and stuff. I don't know. What do you guys think? I appreciate any feedback. Enjoy the look into Armin's really twisted way of thought. Oh and thank you to everyone that has faved and followed this story. You guys really know how to make me feel special!

Armin Arlert. Age, twenty one. Armin was an extremely bright kid. In high school, he was second only to Mikasa. There was only one thing Armin wasn't smart with, and that was love. Even now, he clung to the toxic relationship he had with Eren. If one could call it that. Eren wasn't serious with anyone, or about anything. He was seriously trying to find his place in life. Armin had a plan, and a drive. Eren didn't. He and Eren were like polar opposites, but opposites attract. Right? Well, that's what science had taught him.

After his outburst with Eren, Armin now had the ever patient Boris, vying for his affection. Armin was flattered, but he didn't know if Boris was right for him. The grey haired boy was patient and kind. He offered to get to know one another, as friends, before seeking anything further.

There was a problem with that. Armin was completely, totally, and hopelessly devoted to Eren. They were best friends, it was only normal to seek out a relationship. Right?

Eren was the leader of their group. He was strong and sure footed. (The only thing in life Eren was sure about.) Mikasa, was the glue that held them together, and then there was Armin, bringing up the caboose. He wanted to somehow prove he wasn't weak, but if Eren said jump, he'd ask how high. In the end, Armin was weak, but only for Eren. That thought made him even more upset. This is not the way he pictured things with Eren, and their relationship.

This wasn't so much a relationship as it was a totalitarian dictatorship. It was toxic, and unhealthy, but damn it if it didn't feel amazing.

Sex. Sex with Eren was incredible. Of course Armin had been "faithful." Eren was his first, and only. He was Eren's first , but not his only. Eren was know for seducing boys out of their clothes with beautiful turquoise eyes and a cocky grin. Each time Armin had to bury his jealousy and plaster on a fake smile. And when Eren came running back, in his mind, he would forgive him. Did Armin wonder what sex would me like with someone else? Absolutely. When Eren was gone, had he become a slave to his hormones, and have to pleasure himself? You bet. But other than by himself and Eren, he remained untouched. Kissing Boris was the first time he had ever kissed another person. The feeling was liberating and intoxicating. It was also scary and different.

Did it really matter though? Eren had come running back and Armin had forgiven him. Obviously big shot Levi wasn't all that great if Eren had made love to him last morning he was over joyed. Eren was all his again. He had been nervous. Admitting to Eren that he was in love, and wanted something more Was terrifying. But Eren had responded rather well.

He never realized that sex and love were different. Very different. A night of passion and morning cuddles did not mean I love you. Lust, yes, but not love. To Armin the two of them were in a symbiotic relationship There wasn't a difference because Eren made him feel safe and loved. Even if there were no I love you words exchanged between them, he could feel it with every snap of Eren's hips plowing into him. That was love, a fucked up love, but a love in the end.

He wanted to surprise Eren by meeting him after one of his classes, but he was the one in for a surprise. He passed by the job fair. 'Oh, I should check that out later. Maybe meet some people, and get my name out there.' He thought to himself. He saw Eren, and inwardly pouted he must have gotten out of class early. He was going to call out to Eren, until he saw something that made his heart drop. His Eren, was with Levi, again. That meant that Eren didn't come back to him. Eren had used him. He considered walking over there and slapping Eren, calling him every name in the book, but hurt kept him rooted in spot. Watching Eren smile for a reason that wasn't him.

It hurt. His heart hurt. Tears poured down his cheeks, and a broken sob slipped past his lips. He felt used, dirty, and angry. His body shook in pain and anger. It took a long time to get his senses back into gear. Finally, he could feel his body, and ran back to their room. He buried his face in the pillow and let the devastation wash over his being. Eren was a jerk! A big, sexy, beautiful, jerk. And Armin hated him yet couldn't stop loving him. He clutched a pillow tight to his body. Then he perked up when his phone went off. If it was Eren, he was in for quite the earful. He looked at the caller I.D. It was Boris.

"H-hello." He answered.

"Hey angel, you sound sad. I can call back later." Came Boris' voice.

"No. It's fine. I could use a smile."

"Great. Are you busy tonight?"

"Apparently not." Came Armin's crass reply, but he caught himself "I was going to be busy, but plans got canceled."

"I'm sorry to hear that, but it's great for me. Would you like to go out? Just as friends, and no cop car this time."

Armin smiled "Yeah, that sounds nice. Just as friends."

"Great. I will pick you up tonight at seven."

"Sounds great. See you then."

Armin ended the call, and sighed. He knew Eren might come in wanting him, and he would refuse, and shove his date with Boris, right in his face. Revenge was sweet.
