I imagine Ereri taking their daughter to Disney world and the surprise was them singing this song and the little girl has lights in her eyes, OR Eren starts singing this to his kids, trying to put them to sleep then Levi comes in and they sing together and all fall asleep a big family.
Imagine at the end of the anime if we hopefully have a happy ending Eren and Levi share a glance while jumping on the walls singing this and twirling around while everyone watches them smiling and clapping while the sun sets in the background.
I hate how 90% of the comments are about Eren and Levi. Like, guys. Just acknowledge the fact that Yuki and Hiroshi are real people, or acknowledge that they sing well. Don't just focus on fictional characters. ;-;
Ereri is fckin canon, baby!!! (I love them both T^T) Here I am at 1 in the morning listening to this my inner ereri soul has rest in peace (I was reading some ff of them :">)
I'm just imagining Yato and Yukine both singing this to Hiyori at Capypa land XD and Hiyori being like .-. BUT THEN SHE'LL BE LIKE o////o And Yukine won't be into it at first but then he WILL because he's singing for Hiyori and then YATO X HIYORI HOORAY FOR SHIPS
