Many romance books and manga series, on the other hand, start with one couple, then expand beyond that couple to include others.
The first or primary couple become the "parents" of the series. That is, their relationship is not only the least fraught with problems and hand-wringing, their inherent stability creates a home-base for all the other couples. The primary couple know everyone else and about everyone else.
In Eden Finley's Fake Boyfriend series, Maddox and Damon become the main couple. Once they get over their individual hang-ups, they settle into happy coupledom. Because Damon is a sports agent, he then provides a home-base for a number of other characters who are struggling with sports and romance.

So in Hana-Kimi, although Mizuki's hidden identity runs the series--and she spends most of her time trying to help Sano--they will often work together to help fellow students (and a dog). Likewise, Yoshida and Sato of His Favorite form a fairly united front around which craziness swirls.
It's the reason Monica and Chandler become the primary couple rather than Rachel and Ross--because the center has to hold.
