Ai wo Shiru Hoshi

"Anything is fine as long as I can be with you uncle..."

Due to the disappearance of his sister, Takahiro has to take care of his nephew, Ryo, whom he only met once before, 10 years ago. Aya lacks emotional expression and is reluctant to engage in conversation, and soon Takahiro begins to think that he is irresistibly cute, but Aya has a mark of "sin" that Takahiro himself has to face.

Two lonely people learn "to love" and "to be loved", and become a true family.
