That one~~ It’s called "Kuomiru" (If I Have You), and it’s this song at the beginning of almost every movie version (it doesn’t seem to happen once, maybe 11)~~~This song seems to It was also rated as the most popular music of Conan~~~

When I have nothing to do, I will read out all the theatrical versions and listen to the music one by one to listen to their differences~~~

Chinese lyrics: Your back is drooped and the raindrops are beating on you, which makes my heart ache. I have been paying attention to you with a prayerful mood. If there is only one umbrella in the world, I must find it and give it to you. I can’t do anything for you. It doesn’t matter if I get caught in the rain for you. Please tell me your troubles. There will be dawn after the dark night. There is no non-stop rain in the world, so please believe in yourself. If we were compared to the moon and the sun, then I would be the moon. Only with you can I shine. Don't bear the pain alone. You need to know that I am by your side, because soon a beautiful rainbow will be built in your heart. Because soon a beautiful rainbow will be built in your heart.
