YMMV / I Can't Believe I Slept with You

• Epileptic Trees: Since Chiyo's demotion happens in a flashback without any dialogue, some people theorize that instead of being demoted for her failure, someone stole Chiyo's idea, and she was demoted in retaliation when she complained about it. The "mistake" that cost her everything could be her failure or confronting the wrong person.
• They Changed It, Now It Sucks!: Some readers dislike the localized title, "I Can't Believe I Slept with You!", in good part due to the original title ("Even If It Was Just Once, I Regret It") being used regularly within the story for dramatic effect as the relationship between the characters develops.
