Lousy Existence

Her family left her, without her knowing.
He saved her and let her lived their house.
He kept on guarding her everywhere for her safety.

and that is the order to her grandmother for him to follow.

He doesn't like that idea in the first place but many years came, He used to loved it.

"Lousy Existence, my life became Lousy when I met this girl. Her Existence is my duty to served."

"-and loved it in the ending."
