Each time Eren ventures outside the wall, he brings Levi back a bouquet of flowers.
The first time it happened, Levi most certainly hadn’t been expecting it; the now squad leader running up to him with his hands behind his back, a blinding smile on his face, had been surprising to say the least, but then, from behind his back, he pulled out the most exotic, most extravagant bouquet of flowers that he’d ever seen in his life.
And each time the bouquets grow in size.
But, the time spent outside of the walls slowly starts to grow, days turning into weeks, weeks into months, and Eren’s tired. One day upon returning, instead of the large bouquet of foreign flowers that he usually brings, Eren simply stands in front of Levi and mutters the three words that makes his heart soar: “I missed you.”
From then on, the two spend their time nurturing their beautiful garden of flowers, watching as small seeds start to sprout, and small sprouts start to blossom. And one summers night as the two sit in their garden, listening idly to the song of the crickets and the hum of the wind, Eren presents Levi with a single, red rose, and Levi, lips twitching all the while, reaches out to grab it. He says “yes”.
