Where is the collector? And what is the love key used for?

I bet those were super obvious to most people, but I just couldn't figure out.
Help a brother instead of spending another couple of hours running around, I'd like to move on to steel mode at some point.

In the love tower, between kindom's edge and king's station.

the collector is what the love key is used for.

the key itself is used at the kingdom's edge, it's on the path you'd take to get to the arena.
