Oooh, ok I'll answer according to your criteria : yes, they're both ALIVE, you can actually choose to be his friend or pursue him romantically (because I know he's not everyone's cup of tea x'D), yes, they REMEMBER each other, but TOGETHER? hmm, let's just say it's hard to say since they live on a different period of time, the ending is hard for me to explain without spoiler, so... let's just say if you romance him and get the happy end, you'll at least be TOGETHER emotionally.
