Per cent would be "for each cent". Strange because you didn't address the run on sentence.Try again halfwit. It's more commonly spelled as one word in both America and Australia, numpty. Way to make yourself look like a complete goose.
Keep pretending that the only explanation when multiple people disagree with you is that everyone must be unable to read, dumbass. Think I'll just block you now since you're so full of it. Bye!
Also its common knowledge that most manga readers have poor media literacy. Again you have 3-4 people agreeing with you in this comment thread, but if you look literally anywhere else you find the exact opposite.
You're analysis is just half baked, and follows no logical process. If you have been reading this manga from start to finish and that is the conclusion you have come up with you genuinely have media literacy issues.
Honoka is literally a nothing character. She has not grown she has barely even interacted with him on a meaningful level. Any time they talk to each other its awkward as hell, and he literally thinks about another girl the entire time. If any of this has been a shock to you, you are severely lacking in reading comprehension.
