Can someone explainwhy he did this?

Okay basically long story short I got upset to a guy and said goodnight I live you to him and he put goodnight and I left him on seen because im upset with him and then 30 mins later I put something on my story and with a sad song because it matched my mood at that moment and out of nowhere he likes it, he never liked any of my storied Intel today, why did he do that?, is it a way to spite me or is he liking it because he wants me to stop being mad at him?

Can someone explainwhy he did this?
