It wasn't until recently. The first two were just comedic effect for several chapters. It's been since chapter 300 that it became that up until like 10 episodes or so ago where the author started rotating the characters story. Some of us just acknowledge that it's a LONG time to toss the first two aside and simply have them as comedic effect. Considering it's 250+ chapters... That's years worth of pretty much ignoring the first two having no character development between ZX and JY or their relationship until like 3-4 of their scenes ago.
OBVIOUSLY I know the author is taking their time, bruh. Doesn't mean some of us have to like it. We have the right to our own opinion.
It just didn't flow well and it simply annoyed me that they were ignored for such a long time and their relationship had gone NO where.
I need the main couple to come back cuz like where is the story I'm so disappointed ☹
