I like to look at it like they have been through so much that anything now must seem li heaven and they are cautiously living because of all they've been through.
*like heaven * . Sorry.
Nope, it's just a "saying'. Idk about other places but in our country it was usually said when you experience too much happiness. That doesn't mean something bad would really happen.
And this manga is a certified happy ending one.
I really hope so, this is one of my favorite manga and I WANT that happy ending.
So it appears to be a sweet ending and at first I was super happy about it. Then I reread it and realized Itou said, "I am so happy I am terrified..." This right here blew my happiness out of the water, those three little dots after terrified. I feel like there is some serious foreshadowing there, I hope I am wrong.
