isn’t this the exact same manhwa as silent lover?

ahhh that was a typo i meant silent color... but they are the same series, no?

The style is same. But maybe the story will different ? We will see ლ(´ڡ`ლ)

Yes, it is ^^

This looks like a prequel, since here, it's the first time they met....but why isn't this linked to the silent color in that "other manga by the same author" ?

I checked it in Wecomics, the app that I used to read this story, and it is the same ^^

Nope the first chapters are exactly the same take a look http://www.mangago.zone/read-manga/silent_color/

So this is same but with different title ?

Yup!
