To lie...

Someone commented: I think it's about a guy who want to break up with his gf. Don't know the reason(maybe, they suffer in this relationship,you know this push&pull type relationship), but it's serious,because the guy still love her,but wants to break up("we MUST BE separated"). So,he tells lies for the girl sake,like they will be together. I think the part "I shall be.." represents that he want to protect the girl from being hurt.But after the time goes on(tick tack),it's hard to lie anymore

Oh sounds so familiar ><~~~
