Very nice pixel animaion,
If someone would ask me what I think this is, I would say:
"This is about the passing of passion"
You can clearly see the love, the attraction, and with some things that come on good that they are diminishing with time. Even the things we love do not feel the same as we remember them anymore sometimes - and that is really sad to us. Friends/loved ones help try new things or by just being there for us.
Love the minimal use of colours intertwined in this.
EDIT: On the bright side of the sad animation, the grass at the ending looks strangely familiar :-)
