Tsuki no Kanata de Aimashou

Summer, twenty-five years old. You became a salaryman somewhere along the way without fully deciding to. Looking back at the sky, you remember what you used to think the future would be. On an impulse, you pick up the smartphone from your high school years and open the old messaging app. You type a message to your past self: 'You will regret it.' It cannot be delivered. It is a message to no one. Then the phone responds. Your past self writes back.
