Together forever ? (Shinichi x Ran)

Shinichi Kudo, a young detective highschooler was at Tropical Land with his best friend Ran Mori when he noticed something strange. He witnessed a transaction between two men. While he was going to get closer, another man hit him on his head. The two men in black gave him some poison to kill him, but he woke up later... in a child's body. At that moment, he became Conan Edogawa, went to live at Ran's and started to look for the two criminals that tried to kill him. All of that in secret, to protect his friends and family.
But what if he revealed the truth to Ran, his friend whom he'd been in love with from the moment he saw her?
