Hakanage.

Shinoda is a man of his stripes, carrying a tattoo on his back. He has been a devoted caretaker of Yuuma, a sergeant a year and a half younger than him, since Yuuma was a child. With a heart condition, Yuuma never had a normal childhood and is somewhat out of touch with the world, Shinoda has watched over his first love, his carefreeness and the moment of his sexual awakening.

A love that could die at any moment is waiting for the time of its budding, in a surprisingly close place. Stiff caretaker x intelligent boy, foreign love from a master-servant relationship.
