As Yuki's birthday celebration faded into a cherished memory, I couldn't help but think about her family and the promise I had made to find her uncle, Hiroshi Tanaka. The desire to reunite Yuki with her blood relatives weighed on my heart.

Determined to keep my promise, I decided to hire a private detective. I hoped this would bring us closer to locating Hiroshi Tanaka and uncovering any clues about Yuki's family history.

The detective I hired was a seasoned professional, skilled in uncovering hidden information. I provided him with all the details I had about Yuki's family and asked him to leave no stone unturned in his search.
