There are three parallel reasons:
First,I have the same feelings with the spud.And the lyric says my words.
Second,I love this song,both of the melody and the lyric.
Last,Troye Sivan is a guy who i can‘t my eyes off. He's an angel with pure eyes,pure face,pure voice,pure heart and pure soul.Althought he's a gay,i hope he will be happy forever.
