We encountered the exact same thing in 殺人出産 🤰🔪 Book Club ・ Week 1 - #14 by Kappa421 
So weird what editors come up with…
@Hantsuki Thank you very much for the detailed explanations! It all matches my expectations, because, Japan 
but I didn’t know all the details. Great to have a first-hand report on this.
Thanks for the heads-up! Will be on the lookout for any issues.
