Help please

Help finding this hunter manhwa.
There's a scene where the MC who has traveled to the past is against the awakening centre and agrees to awaken people instead before it opens. He goes to the awakening centre and sees people being awakened and they don't awaken to their full potential. Like there's a guy who has a music skill but doesn't awaken with it because the centre isn't good.

I always thought it was s class hunters I raised but I recently reread and it isn't, although there is a scene which is very similar. Maybe it actually is in s class hunters and I just skipped over it either that or I just imagined this.
