You, aka Shinichi, and Ran were best friends since childhood. She was the head of the karate club and knew you had a liking for solving cases, which Ran would always roll her eyes at. However, despite you being a tease, she found you cute and really liked you...

One night, you were at Tropical Land with Ran, it was right after you had solved a murder case that occured on the roller coaster ride. Suddenly, you spotted a man in black running towards the tunnel leading to a restricted area. It was the same guy who was on the ride with you and Ran. You decided to follow him, and Ran tried to protest, but you went anyways.

Later...

Ran had been waiting for some time, and she was concerned. She didn't know what was happening to you back there.

"Where could he be? Shinichi never takes this long to solve a case..."
