Hi there! So after trying to unsuccessfully convince myself to not start a new fanfiction- here I am. I just love these two so much and it was that love that drove me to write this, (also because I ran out of Eremika fanfictions to read). And I got this idea like at 5 am as I was on my way to my college chem class and I couldn't shake it from my mind, so I had no choice- but to write it down. Excuse my errors, English is not my first language and I usually write on the go with my schedule. I will try fixing any as soon as possible.

Note: I will start this story in T for now, but might up it to M...-We'll see (smirks)

Chapter 1. RSVP

Mikasa shuffled forward, her arm shooting out into the air, waving drastically across the headlights of an oncoming taxi.

She tightened her unbuttoned coat around her with her free arm, as the early night air was beyond freezing at that moment, but she had been in such a rush this morning- out of fear of missing the cruise ship departure, that she hardly had time to properly pack everything as neatly as she wished she had or much less take in consideration her own appearance this morning.

She was beyond relieved when the taxi slowed down and stopped right in front of her.

"Thank you!" She managed to breathe out, as the man got out of the car to get the rest of her bags.

Once inside the taxi, and after giving the taxi driver the directions to the port, she finally pulled out her phone to see the time.

It was still another two hours until the departure of the ship. If her calculations were right- which as an Ackerman tended to always be, she would definitely arrive just in time.

"Going on vacation?" The taxi driver asked as he drove.

Mikasa quickly shook her head. "A wedding actually."

She tucked her phone down, not bothering checking the pile of messages that were pilling on her inbox. She knew that half were probably from Sasha as she remembers scanning some of her messages last night.

You're coming Right? -S

What do we even pack? Do you think they'll have food?-S

Nevermind-of course they'll have food-it's a cruise ship! But will it have ENOUGH FOOD?!-S

Mikasa! You have to go! He's your best friend!-S

Mikasa what will the weather be like in the ocean? -S

You're still coming right? (sad puppy face)-S

Wanna carpool to the port? -S

?...-S

Mikasa you need to call me so I won't forget to set an alarm? -S

Mikasa? Are you there?-S

Mikasa-Mikasa-Mikasa MIKASA ACKERMAN!...Mikasa?-S

She had shut her phone off after that last message had arrived. Once again looking at her empty suitcase on her bed. She had stared at her suitcase for hours contemplating whether to go or not. She had wanted to deny the invitation- not because she had any hard feelings on Armin or Krista, but because she was afraid to see all her old friends again…and…of course him.

She had walked away from all of them a long time ago, had moved many miles away. And although it pained her to leave, she knew she had to leave. She had made the right choice then.

She was never planning on going back or seeing her old friends ever again. She had been doing fine, living on her own with the occasional visit from her older cousin Levi or Sasha, but she was doing okay. Sure, she was lonely, but she was no longer in the way of their lives. Not in the way of his life.

Mikasa had been in a content stable state in her life, but then that beautiful encrypted card had arrived in her mail, and everything that happened years ago returned to her.

In the end it had been that same card and that message scribbled on Armin's wedding invitation that made up her mind to decide to go.

Please come, Mikasa,

Didn't we promise each other to see the ocean together? -Armin

That nearly took her whole heart away. How could she say no to Armin when he wrote something so meaningful like that? How cruel of her to deny him, and yet her mind had held on to a trace of still saying no until she read the very last note.

P.S. Eren said he couldn't make it.

She had wondered why Eren wasn't going-Did he have work? Was he dating someone?- she had quickly discarded those thoughts. Reminding herself, that it was not her business anymore.

Eren was part of her past, a thing that never was or meant to be.

One thing was official though, she was going.

One of them had to go, and if Eren was not going for Armin's wedding than she was definitely going.

The taxi arrived just minutes before the departure of the cruise. The driver had wished Mikasa a good trip, as she got out of the taxi, but Mikasa was too caught up with the sight in front of her, that she never responded back. With her eyes wide open and her mouth slightly set ajar, she was absolutely speechless.

The ocean….-

How many years had she spent wishing to see it and here she finally was. Now looking at the glistening endlessly deep ripples of water holding the immense ship up. The ocean looked far too vast and powerful- and so unknown to her that she couldn't quite capture the exact words to even begin describing it.

"Last boarding call! Please hurry!30 Seconds till departure" One of the crew workers called out as other workers already begun releasing the ropes attached to the ship.

A few others rushed inside the S.S Titan.

Mikasa acted then, snapping out of her reverie, she gathered her bags and ran up the boarding plank right as someone in the crew yelled out that the time of departure was now.

"Mikasa Ackerman," she huffed out her name, flashing her ticket.

"Ah yes, Mikasa Ackerman, you're the last one for Armin's Party Group," A crewmember with a clipboard checked her name out, and gave her a key with the room number tag attached to it. He began signaling the direction where her room was stationed. "Your room is just in the lower deck of the 3rd level in room 372B with-" suddenly the crewmember got distracted by a set of rowdy children who were trying to sneak into the cruise ship. "Sorry miss excuse me- Hey! Stop that right there!"

Mikasa glanced at the key and gathering her bags, she began to follow the directions in the halls towards her room. She wondered why she hadn't seen Armin yet. Although there were a couple of people shuffling through the ship looking for their rooms or exploring, she has yet to see a recognizable face.

After a couple minutes of searching she finally located her room right at the very end of the hall of the 3rd floor level. But right as she was getting closer she heard shuffling at the other end of the room.

Someone else was in her room.

Frowning, she double checked her key and the door.

372B, this was the right door, it was no mistake. Her key even had the name Mikasa Ackerman written on the tag.

Whoever the other person was must have made a mistake and gotten in her room by accident.

Sighing, Mikasa realized that she would have to set everything straight, after all it was better if the other person got back to their own room before that said person started unpacking.

Turning the knob to the door, she pushed the door open strongly in order to get the rest of her things in at the same time. She didn't immediately make eye contact as she murmured with both a sense of calm and directedness.

"Excuse me, this is my room-"

Her words were cut short as soon as the door busted open and she got to see who was inside.

Mikasa wasn't sure what she saw first, the flash of his shirtless tanned skin flash right into her point of view or the surprised green eyes that darted in her direction upon her sudden arrival.

Mikasa whole body stiffen into stone in a fraction of a second.

It couldn't be- no-no- no it….couldn't…be-

His own expression expanded in even further surprise as he looked straight back at her.

"Mikasa?"

His voice hit her like a brick of memories. Suddenly she found herself rethinking about how many times she had fantasied on just hearing his voice. But this wasn't a dream-

"E-Eren?!" She gasped her whole breath in that instant taken away.

Everything suddenly started shaking as the floor started moving below her- the ship had set sail.
