Aito, a second-year high school student, was starving for affection.

His mother was constantly working and paid him no mind, his younger sister had ignored everything he said for the past six months, and even his childhood friend, whom he thought was the only one who showed him affection, announced they had fallen for someone else.

Even so, Aito continued to seek affection.

However, one day upon returning home from school, he witnessed his mother and sister talking.

His mother, who usually only wore a tired expression, was conversing with his sister, smiling.

At that moment, his heart was deeply wounded.
