Everything else aside—what a diverse set of art styles in one chapter!
A reasonably standard-ish manwha look for most pages, yet we get both striking realism and utter cartoonishness, and a variety of both eastern and western styles; the landlord gets the late-80's disney anthropomorphic creature treatment, her mother gets Alphonse Mucha-esq portraits, her employer gets yet another style that I can't put my finger on but is implacably familiar... And that's not even all of them! And it all works together!
