Happy Birthday, Eren!

The young titan shifter scratched the back of his neck confusingly.

He was walking every where around the HQ. Yet he hasn't seen a single living soul. He was sure that there was training today. He checked every nook and cranny, even the stables (he was hoping to find Jean there, but he wasn't). Eren found himself in the courtyard. The day was still young and he pondered what he should do at the moment. Now that he had a bit of thinking, he realized that he didn't have certain hobbies he'd enjoy doing. All he has ever done is clean, train, clean, and train. Well maybe he questioned his life every now and then, but his friends were there to support him.

He was so lost in thought that he didn't notice a certain figure who sat next to him.

"Oh, Sylvia. I didn't see you there." He greeted with a timid smile as The Commander made her wings disappear.

"Did I surprise you? I'm sorry if I did. I saw you sitting here alone, made me approach you." She said with a smile, Eren shook his head and turned to gaze at the horizon. "How come you're alone, Eren?" 

"Well, I don't actually know. I've been looking for everyone all morning. I haven't seen anyone aside from you." Eren answered.

"Really? Where could have they gone?" The Commander beckoned Militar, The large green horse that usually follows her around, to lay down beside her. The horse followed and gently placed its head on her lap. Eren thought the horse acted like a dog, but he shrugged it off. They remained silent for a while, The Commander lightly brushing Militar's mane with her fingers. 

"Eren, it's your birthday today, remember? Happy Birthday!" The Commander greeted.

Eren grinned and nodded. "Thanks. But I don't really celebrate my birthday too much. When I was young, mom would allow me to eat breakfast in bed. Then Armin, Mikasa and I would play in the near by fields. Armin's grandpa would let us ride his horse, when we get home, dad would give me a really cool but weird present. When I turned ten, mom knitted me a scarf, dad gave me this really comfy jacket that I used to wear every time I leave the house." Eren stared at his hands for a second, frowning. "But...I guess I won't get presents from them. I gave Mikasa the scarf mom knitted me."

The Commander immediately ruffled the latter's hair, earning a confused grunt. Eren turned to her and saw a neatly wrapped box in front of him. "Here ya go!" She handed him the box, which had a few rose petals on it. Eren gratefully accepted it and gave thanks. He opened it and got a bracelet, the charm on it was the Survey Corps' logo. He thanked The Commander once more. Militar stood up, nuzzling its nose on her hair, The Commander stood up also, she gave Eren a hand and yanked him up. She then got on Militar.

"It's about time, follow me, Eren."

Eren asked where, but The Commander just smiled at him and Militar began to move. The trip was silent, Militar's galloping was the only thing heard. They reached the main meeting room of the HQ. Eren raised a brow, is everyone here? He checked this place three times! He helped The Commander down, and she made Eren open the two large oak doors. He did so ever so slightly. And was taken a back by the scene before him.

"HAPPY BIRTHDAY, EREN!"

Confetti flew down from the party poppers, the large banner containing the birthday greeting and Eren's name hung on the opposite wall before him. On the ground, before the table filled with different kinds of food, was all of Eren's friends. Mikasa and Armin approached him first, they tackled Eren for a hug, greeting him over and over again. Next to greet was his fellow Trainees, Jean, Connie, and Reiner gave him a pat on the back. Annie shook hands with him, Marco ruffled his hair and Sasha gave him a bone crushing hug. Eldo and Gunther gave him a bro hug, Petra hugged him and gave a small kiss on his forehead, Oluo pinched his cheek, giving him advice and wishes when he bit his tongue. Hanji screeched when it was her turn, she picked him up and spun him around, Erwin stopped her when Eren was getting dizzy, the Survey Corps' Commander ruffled his hair and shook Eren's hands. Levi admiringly poked Eren's cheek ever so slightly before he ruffled Eren's hair also.

Mikasa and Armin brought Eren's cake to him. They all sang the song, and Eren was making sure he wasn't going to cry. When they ended, Eren had the biggest grin on his face.

"Wow....I just....guys this is, this is incredible. To have you all go through this trouble, I'm sorry and I'm grateful." Eren sniffled.

"Well, are you going to make a wish or do I have to kick that cake to your face? Besides, The Commander was the one who thought of this idea. Now hurry up, I'm hungry as fuck." Levi complained. Eren laughed this off and closed his eyes, making his wish.

He blew on the candles and everyone cheered when it went out. The feast begun, everyone was having fun all together. During the night, the adults had a drink, messed around with their subordinates for fun. Eren went outside for some fresh air, he saw The Commander talking to a person.

"Ah, (y/n), where have you been?" Eren greeted. You turned around and smiled, you hugged Eren and greeted him. 

"Sorry~ I had errands to do in the other world. I hope you'd forgive me, Eren." You apologized. Eren shook his head and ruffled your hair.

"Jeez! I'm beat, writing sure can be tiring, don't you agree?" The Commander said, stretching under the moonlight. You and Eren nodded.

"Oh I know! How about a 3DMG Race around the walls? Winner gives all of their cleaning duty to the Loser!" You proposed.

"That sounds like fun! Let us join in!" The 104th Trainees said, all equipped with their 3DMG.

"Now now, just because it's the night and no one's awake doesn't mean you lot can go by yourselves." Erwin said, they turned to see Levi and his squad along with Hanji, all equipped with their own 3DMG. "Let us join in the fun too." 

The Commander grinned and gave Eren his 3DMG. He equipped it, and they begun to fly. The Commander followed them, flying next to the flock of Survey Corps soldiers.

It's the baby's birthday!

He's so close to become legal.

People like Levi can marry him! xD

Happy Birthday, Eren!

Eren: T-thank you.... 0////0
