I think the message at the end is basically "who cares." Because it really doesn't matter. It is interesting though that in every discussion about this oneshot I've read, it's always her fidelity called into question based on something she may have done 7 years ago as a teenager. So what if she cheated on her back then, that doesn't say anything about her as a person now.
Asami on the other hand concocts this elaborate revenge scheme about dating someone she despises, giving up her job, moving away - all just to get some comeuppance for being dumped in high school? That's insane. That Chiharu sticks around after learning that speaks for itself.
