Drift Bottle in the Wishing Fountain

I finally arrived in Rome, which I have wanted to come to since I was a child, and I was still standing next to the Fountain of Happiness, which is the legendary Trevi Fountain!~~ There is a legend about the Fountain of Happiness. As long as you turn your back to the Fountain of Happiness and throw a coin into the pool of the fountain towards your left shoulder, your wish will come true. However, the wish made with the first coin must be to return to Rome, and the wish made with the second coin will come true. Unexpectedly, something happened before I even made a second wish.
