Levi Ackerman had lost his hopes of his life getting happy or better. He doesn't even try to make something out of it. But one week, just seven days, will change everything.

"Things will be different at the end of the year. Hopefully better and not worse, but just remember that I'm always here for you and I will never leave you. I promise."

This is not about an empty promise that has been broken but about the hope behind the words and the love between two best friends.
