Years ago I heard a love song that I thought was sung by Taryn Mannings brother Kellin, but can no longer find any mention of him singing solo at all. So I might have the wrong artist.
In the video there is a blond guy sitting on a bed singing a slower but popish love song, about...maybe...not being able to go on without her...or...loving her till the end. Some woeful unrequited or lost love song done in the early 2000's. Maybe 2003 or so and just a one hit wonder song.
