No doubt about Clara, she's a total ball of joy but the real best girl is within us, specifically irumi is the best girl and the only girl capable of handling iruma at his best and worst
It's kinda uncanny to see this version of iruma since we already see how iruma is way more mature in the og series as the story already progressed further, like i'm not used to seeing the old overly naive iruma like this
Prediction for next chapter: Ameri randomly meets Iruma before she discovers he's the Mafia boss and develops a crush on him, leading to a crisis of emotions when she goes to confront the group. A tried-and-true trope used in several mangas.
