The Japanese version of βhow cuteβ. The character Kaguya Shinomiya uses this a lot in the manga called Kaguya Wants to be Confessed to, otherwise known as Kaguya-Sama: Love is War.
It is Shirogane Miyukiβs (another character) least favorite saying of hers.
Kaguya: O kawaii koto.
Prez/Shirogane: AHHHHHHHHH
