Man, this is one of the cutest things I have ever read. They're one of the best couples I've ever seen. So f*cking precious! I'll 100% re-read this in the future.
Ao Haru Ride
One of my absolute favorite books of all time. The artwork is absolutely stunning, which is an added bonus. It is extremely traumatic at times, and it is very slow-burn, but Futaba and Kou's feelings are clear throughout the entire series; they were each other's first loves and they are soulmates. They might not have been aware of it the entire time, but it was clear to me as a reader that they never fell out of love. In short, they were always going to end up together, and, man, am I happy they did.

I absolutely loved it!
