Are you really saying a chapter where Rei suddenly changed attitudes after constantly rejecting Mahoro is meaningless in the context of an affair? Of all chapters to have this complaint, this one feels like the least appropriate to have it.
I mean don't read it if you don't like it obviously, but damn, feels like we're reading a different manga.
Reminds me a bit of the comments begging for spoilers of who did it. Do people just not have the attention span to follow a story unless there's guns and explosions every chapter?
