Interpret the song however आप want लोल but the video revolves around The Truth epi and Mulder is looking back on everything he and Scully went through.
It has been awhile so I can't remember too well but I think the story was about Mulder and how he hurt Scully at times but through everything she stayed द्वारा him. And she ultimately helped him...something like that लोल Hope आप like it.
