From Kaguya-sama: Love Is War:
As you know (Gasai) from memes, Kaguya often says (either actually or in Miyuki's imagination) 'お可愛いこと' (o kawaii koto). You can even see like a compilation here.
Miyuki seems to say something similar (either actually or in Kaguya's imagination) 'お可愛い奴め' (O kawaii yatsu-me ?)
From the anime S01E11 (eg here)
or from the manga Chapter 42
Questions:
What's the exact rōmaji here? O kawaii yatsu-me? O kawaii yatsume? O kawaii yatsuume?
What's the difference? I'm guessing still 'practically they are used synonymously' again like the 2 true love's...but then theoretically though...?
