Sad piano pieces/piano heavy songs?

Hello, I am looking for a piano piece or piano heavy song to play in front of my school. It doesn't need to be classical, but It needs to have a melancholy feel to it, a sense of vulnerabilty, sadness, maybe with a dash of hope? Something like The river runs through you by yiruma?

song to play in front of my school. It doesn't need to be classical, but It needs to have a melancholy feel to it, a sense of vulnerabilty, sadness, maybe with a dash of hope? Something like The river runs through you by yiruma? Or something Bon iver, sufjan Stevens, the middle east ish. Sorry, I don't know many classical composers. I am not an amazing pianist but pick things up quickly if I like what I am playing.
Something like this:

I would be eternally grateful if someone could help me out.
P.s I will be playing in front of someone I have loved for 4 years and have never told. I kindo wanted an emotional sad piece... As our situation is complicated.
