They are still part of the story and they do often get chapters of their own or half part of it but their acceptance phase is over...now author does not touch that part instead they shares their 'after that acceptance' moments and their bond with each other in general like how it was shown in the recent chapter even. Lol

I'm sorry it wasn't just my opinion that i shared above...their are actual/ proper chapters dedicated to first couple accepting their relationship and the growth of their relationship after making their relation official. I faintly remember their first kiss and 1st seme drawing his and uke's drawing on their school wall too ( something like that).
Love the 2nd couple contents we are getting .. but would wanna know the progress of the first couple now
