Conan
But in fact, this is only a superficial ideal, because in the final analysis, we will find that he hopes that black organizations will stop hurting others, and his essential purpose is to become more peaceful. In addition, because he was framed by Gin, he also became Conan as a pupil.

But in the whole process, we all saw the sadness that he couldn't see Xiaolan. Even if he becomes a child, he still has to accompany Xiaolan. He guards Xiaolan in another way, so this love is touching.
Kudo Shinichi
So everyone has been calling on Conan to return to Kudou Shinichi as soon as possible, and then don't make Xiaolan sad. So Conan is now trying to solve the case, and he is particularly eager to get more information about the black organization. The fundamental purpose of all this is to be able to be with Xiaolan aboveboard.
Now Conan is afraid to tell Xiaolan his true identity. We know that he is worried that Xiaolan will be involved in this negative matter, and Conan can't guarantee that he can fully protect Xiaolan, so he just doesn't dare to tell Xiaolan. He is also very sad, but there is no way. He doesn't want the girl he likes to be hurt a little.
So now I see that Conan has been making special efforts to this end, including making Haiyuan Ai constantly develop an antidote, in order to get along with Xiaolan. He also investigated black organizations to restore his identity and then stayed with Xiaolan.
Therefore, after analysis, Conan's greatest ideal is to restore his original identity and then live with Xiaolan, so that Xiaolan will not be sad because he misses him, and can also protect Xiaolan's safety well.
