At the beginning of the chapter: Oh, the crazy ex-girlfriend enters. Cue drama.
End of Chapter: Nope, crazy WANNABE-girlfriend. The yandere is strong with this one. Slap her down, Rupia!
The timing of that lady thinking "he'll be a beast in bed" was funny. I know Rupia's shiver was supposed to be her sensing that woman's bloodlust, but you could also see it as a sudden intuition of what she's in for with Maou. 🤣😎
