I don't remember it clearly, but I think they also exchanged rings.

So, this is why author now has to focus on other plot lines, like imouto's.

Which is not a bad thing, since, for example, Kunimi Yuuma is still in need of a new gf :<
And there are even some nice candidates, like a certain science girl.

Spoiler for vol 9:

vol 9 well, this is not just promise, they are going for that. And not small part of this volume is focused on Sakuta mother. Plus we get new girl at the end of the volume. And it don´t look like he is going to focus on other plot lines.
