The rare candy means you have to level him up, and if there is a specific number, then that means the mon evolves at that level specifically. In this case, there isn't, so you only have to level up a Tear-eye while it has zero friendship value.
Story
… am I… am I doing something… wrong?
Tear-eye thought this to itself after being shunned away by the person who it tried to console. This wasn't the first time, either. Its seen a pattern: more and more humans are ushering it out because "they need some time to themselves, thanks". It was hard for him, but he put up with it every time. Not this time, though. This one was the last person he wanted to see.
Humans can't just be incompassionate… no… no, they… can… they can just be incompassionate
It looked down on a miniature shimmering lake nested in a pothole, the rain fogging up the reflection it saw of itself. Even when it blocked the rain out, it still couldn't quite see itself as… itself.
They HAVE to be.
It knelt down on its bubbly body, staring deeper into the reflection.
They just don't like me, do they? Of course not. Of course they stomp me out like a cigarette butt. I'm always the one that's thrown into the dirt, the one that nobody cares about, the one that's left to rot.
His good eye shook with every strong word he said to himself. His cross eye twitched in tandem.
Why do I even bother? Why do I go through the trouble of caring about these jerkwads, if all I get in return is a punch in the gut? Why, why, WHY?!
It forced its head on the pavement beside thrice.
Why… should I even care? Oh, but of course. I shouldn't have. I shouldn't ever have. It's stupid. THEY'RE stupid. FRIENDSHIP is stupid. MY LIFE IS STUPID.
Once again, it slammed its head on the same pavement.
It's pointless. It's always been pointless, and always will be pointless. I shouldn't be the Empath Pokémon, because it all goes to crap.
At that very moment, as if Jirachi suddenly granted its wish, it shone a brilliant light from both of its eyes. Its plasma went cold; sure enough, downward-facing spikes suddenly emerged – suddenly grew. Its eye changed shape, and the iris changed colour – a cool blue to a burning red. Its body extended, growing more parts and more of these spears – these icicles.
Then, the short-lived metamorphosis ended.
It looked down on itself once more.
It wasn't a cute tear ghost anymore.
It was a big, menacing, bitter tear ghost.
Empath had turned Sociopath.
Tear-eye had gone. Bittear-eye had come.
Bigger. Bitterer. Better. Much better.
