Another outbreak after outbreak just a few years later, AU

You were Ellie's girlfriend for a couple of years now. But there's one thing you didn't know about her. She was saving money for your 22nd birthday. You really wanted to go to Japan for a while now, and Ellie decided to fulfill your dream.. You were so happy when she told you about the vacation, that you actually couldn't sleep that night.. but cuddle with your girlfriend all night.

The flight was nice, you guys were in the first class.. thanks to your amazing girlfriend. When you finally arrived, you went to get a hotel room and rest for a bit. But a few hours after, you really wanted to go outside already, and explore...

In the evening, when it was already dark outside, you went to nearby beach. It was hot summer night, the stars shining at the sky, and you with your beloved hand-in-hand walking at the shore.

"I wish.. We could stay in this moment forever." Ellie mumbles and her grip on your hand tightness.

But this is where the story gets dark. Screaming from many citizens was suddenly heard.. You both look the direction where it was coming from, and you see that they're running away from.. something. You look at Ellie to say something but she stays silent.. her eyes wide open in shock. She already has been through this, and so you were.
