I don't know if this is exactly what you are searching for but "My Lovely Bunny" is a really sweet one in which they both long for each other. Not in like "we have a conflict, and so I long to see you", but just in, "i'm obsessed with you, so every day, every hour i'm just thinking about you".
Don't recommend reading the last chapter. But apart from that, I love every bit of it.
