RainySeason's manga / #Slice of Life(2)

It's about brothers who try to determine their true feelings about each other. Minoru, who has always been sending letters to his little brother, Yutaka, who always awaits each of his letters until one day Minoru comes home. It's also really sweet how it shows both perspectives on how they are thinking about one another.

Starts off lighthearted then it goes really emotional and heartbreaking. One who decides to make a fresh start and another who is trapped in stalemate.
