Always and Forever, Anonymous.

Gun had always been receiving letters from an unknown person who insisted on hiding his identity.
It's been 7 years since he stopped receiving those letters.
The same amount of time had also passed since he lost hope from life as well.
It wasn't until 7 years later when he realized who it was from, after being disturbed by an deafening loud knock on his door one gloomy morning. With a box being handed to him filled of old memories, and news regarding his old high school rival.
