Yeah I'm giving it until the next update to decide if I'm going to do this. I was so annoyed when I saw that this update was heavily focused on the second couple instead of progressing the main couples story. Hell if the sequence was switched I'd be less annoyed. Starting the chapter with them as the focus really got me.
Right now there are two active conflicts going on with the main couple and instead of wrapping at least one up to start a domino effect that would lead to them resolving their issues and working on their relationship, I had to watch a couple that served nothing to the plot. And that's what's extra annoying, their story did nothing to progress the plot of the main couple.
bro idk... i think i'll marinate this manhwa. i don't understand why the author adding the new couple when the main couple still not resolve their issues
