Prologue

It had been a year since the Black Organization had been brought down, and Kudou Shinichi returned to his life as a high school student and detective. When he had come back, he had told the truth to Ran, and she had taken it rather well. They started to hang out as a couple for a few months. However, they could not continue their relationship. After living with Ran for so long as Conan, his feeling for her had become that of siblings. Ran felt the same. They agreed to break up but stayed close with each other, both as best friends and as family. That was all Shinichi could ask for from her after making her waited for him for so long. They lived the same as before, but with an exception that he came over to Ran's house every Friday to have dinner with the family, now that her father, Mouri Kogoro, had grown fond of him since he had lived with him for so long and also considered him as a family.

After returning to school, with the excuse of going undercover for a big case, he had to make up a lot of works so that he could catch up with his classmates. Fortunately, in the end, it all turned out well, and he is in his final year at Teitan High School.

As for Haibara, she did not drink the antidote to return back to her original body. She wanted to stay as an elementary student so that she could have a second chance in life. She still hangs out with the Detective Boys. They had told them the truth about how Shinichi and Haibara had become shrunk and they did not turn them away. Now, they were still best friends and Shinichi would hang out with them or help them solve cases whenever they asked him to and he was available. He treated Ayumi, Mitsuhiko, and Genta like his siblings. He would give anyone that hurts or tries to hurt them hell.

Since his return, he had continued to solve cases, with only one exception. He had been going to Kaitou KID's heists more often; and he even had his own personal invitations in his mailbox from the thief everytime, to Inspector Nakamori's annoyance. However, the Inspector knew that with Kudou Shinichi at the heist, they would get closer to catch the thief themselves, so he had allowed Shinichi to join in and help catch KID. Aside from him, there was also Hakuba Saguru. He was also a detective, but he devoted himself more into catching thief than Shinichi himself. While it was true that Hakuba's main interest is Kaitou KID, Shinichi had a feeling that he was looking for something else, too. Something that he was not going to revealed any time soon.

While he loves their chasing game under the moonlight at the heist, there was actually something else that he refused, under any circumstances, to mention to the thief. Ever since his time as Conan, he had actually developed feelings towards the famous Kaitou KID. He had denied it for the longest time, but now he could not push the feelings aside anymore. Each time he attended the heist, the feelings increased until he was head over heels for the thief. However, he promised himself not to tell the thief about how he feels in fear that he might scare him away and lose the opportunity to meet up with him again in the future.

"Besides, he is a thief and I am a detective. He will never return my feelings so why bother," is what he said to himself every time he found his mind drifted off to think about the famous Kaitou KID.

One morning, while they were about to have their first class of the day, Ran had asked him to come with her to Ekoda this weekend to join her with her new friends that she made when she followed her father to Ekoda for business. "You need to take a break from all of those cases and hang out more with actual people, not police officers," was her excuse to make him go with her instead of staying home solving cases and rereading his Sherlock Holmes' books. Well, what she said was not wrong, he has been a little isolated from everyone nowadays and only left the house for school or when he had a call to help solve a case from Inspector Megure.

"Maybe this trip will take my mind of my crazy thoughts about the thief." And he agreed to come with Ran and Sonoko on their trip to Ekoda that weekend.

Little did he know, this trip will strengthen his feelings for the thief and a revelation to a forgotten promise that he had made long ago with a certain magician.
