Who copied Leo from Yico Zeng? That song?

The melody of Yico Zeng (Leo) is very similar to pure music (sky), so everyone thinks that (Leo) copied (sky).

But it's not necessarily true. Because today I finally found an English song (the theme song of stand up champions) twenty years ago, much earlier than (Sky) and (Leo). Let's listen to the melody The most beautiful melodies in (Sky) and (Leo) are almost English songs that start from slowing down.
