I can't even. I've been fucking restarting this for 10+ years.
I loved the breaker so much. Like, so, so, so, so much and then the very last chapter happened.
So, yeah, all I want is their relationship to be fixed as well, but I never managed to get this far before quitting, because everything about this upset me. Did you manage? Can you spoil me if it gets any better? I wanted to give Eternal Force a try, but apparently, it's needed to have read New Waves as well, even though I gathered there's a new protagonist.
Eternal force is very much a continuation of new waves, there is a " new protagonist " in eternal waves but imo it's more of a sub protagonist and the focus is still on the disciple, like in new waves. The new protagonist is just showing a new perspective to look at what they went through/rediscovering the past and the martial arts world.
New Waves is the disciple's perspective and his character arc specifically and Eternal Force is the disciple settled in his own new role, being encountered by this sub mc in a different light at this new point in life. The dynamic of goomoonryong and his disciple is in focus in both parts so reading both is not a waste. But if you only have energy for one, in Eternal Force the dynamic is closer to repair again(as it is the most recent chronologically) and gives goomoonryong satisfying screen time.
I just restarted New Waves for the umpteenth time, remembering from page one why I hated it so much, but I'm not yet giving up. I'll keep trying. Maybe this time I'll keep plowing through.
Anyway, thanks for you information, so I know I can just skip past it if I can't get through it to see if Eternal Force is doing better than this.

I'm here for goomoonryong's relationship w his disciple please
idc how but fix it ...
