Shawn Mendes is trying to get the attention of his crush on this pining love song.

I can treat you better than he can
And any girl like you deserves a gentleman
Tell me why are we wasting time on all your wasted time when you should be with me instead?

Shawn is insistent that he can love the girl better than her current boyfriend.

This song was co-written by Shawn Mendes, Scott Harris, and Teddy Geiger. Harris explained to Songwriter Universe the process of writing the tune. "I remember we wrote it in LA," he said. "Teddy had worked with Shawn before and Shawn was excited to get the three of us together. I've known Teddy for a while. My band actually opened up for him for six weeks one time. The vibe was immediately right. We all get along really well and it kind of came right out. It was actually a full-on reggae song until we switched the guitar part right before we recorded the demo."

Other songs about a guy who has a crush on someone else's girlfriend include "Jessie's Girl" by Rick Springfield, "My Best Friend's Girl" by The Cars and "She Will Be Loved" by Maroon 5.

Shawn gave the first TV performance of the song at the iHeartRadio MuchMusic Video Awards in Toronto, Canada on June 19, 2016.

Shawn has known Taylor Swift since she brought him on her 1989 tour as an opener. On his 18th birthday Taylor serenaded him with this song on Snapchat.
