What does...

To me love means a deep appreciation and affection towards someone as a whole instead of the sum of their individual traits. When a person is irreplaceable in your life just because they are themselves. Like if you lost someone you truly love, and this person made you laugh, and smile, and paid attention to you. Surely you can you can go out and find other people out there that have the personality to make you laugh and smile, and also pay attention. And with forums out there for everything nowadays I bet you could find someone with most the same interests and hobby's of the one you lost (Not that I suggest doing this, it's rather unhealthy.) But even if you find the exact replica of someone you loved, it still wouldn't fill the void of what the person meant to you, cause, anyone else, is still not them.

love is the relationship between pokemon and me. XD

love means traveling back in time watching her die everytime just for the slim chance maybe, just maybe, this time u can save her

It was Steins;Gate. Plus in those desperate measures the human mind wants to be optimistic. Plus not sure if that was love in that case. :p
