Woah, page 9 Yamato says: "We were always fighting, huh?"
Looking back how Honoka broke up due to some potential upcoming disputes... and now he, being with Suzuka, the fighting is heavier and more often then there would ever been with poor Honoka...
Aside him not ever been really interested in Honoka in the first place, going the reasonable way instead of the emotional back then, would have resulted in a far more pleasant relationship.
But then again we'd not have any story to read since about 50 chapters anymore.
