What's the name of this manga?

I don't really remember this manga much but I know the male lead dies and his lover ties something around his wrist so they can find each other. Then there is a time jump and he is now been reborn and he is a teenager when they meet again. Sorry this isn't much to go on but I'm lucky i remember that much xD

It sounds a bit like Kimi ni Sasayaku Mirai.
