Ai wo Shiru Hoshi

"Anything is fine as long as you can be with your uncle..." Due to the disappearance of his sister, Takahiro must take care of his nephew, Ryou, whom he met once 10 years ago. Ryou lacks emotional expression and rarely responds to questions, yet Takahiro begins to think that he is irresistibly cute. However, Ryou has a proof of "sin" that Takahiro himself has to face. ...Until the two who were lonely began to learn how "to love" and "to be loved." (Source: J-Publishing, translated)
