I'm looking for stories where the main lead(s) have experienced a love that they have difficulty forgetting before they meet each other (and possibly also when they've started their relationship). I know this is quite a commonplace among shoujo manga, so I'm just looking for manga where it's quite a significant centre-point of the plot... or for shounen/seinen where this happens.

e.g. Shinobi Life, Spicy Pink Omae ga Sekai wo Kowashitai nara, Bride of the Water God, Inuyasha, Chrno Crusade, etc...

Thanks in advance :3

Goong
Kimi Dake ni Ai wo
Bokura ga Ita
Parfait Tic
Do You Want to Try?
Immortal Rain
Oyayubihime Infinity

Does NG Life count? Lol.
I second Bokura ga Ita.

Let a brother THIRD Bokura ga Ita!

Do you know what people did in the old days when they had secrets they didn't want to share?

They'd climb a mountain, find a tree, carve a hole in it, whisper the secret into the hole and cover it up with mud. That way, nobody else would ever learn the secret...

chokotto sister comes to mind.

Hrodulf and Bjornolfr, you will not be forgotten.

If I had a fantasy self, it'd be a tentacle monster.
