Yuta's Adorable Egg Tart Challenge!

In the Korean comments

One top comment reads, in translation, “Does Yuta know that losing to his embarrassment and collapsing at the end is the ultimate natural cuteness?” Another pinpoints the shoulder lift timed to a meow and jokingly calls Yuta the top student in “aegyo studies.”

What the words mean

애교학 수석 (aegyohak suseok, “top student in aegyo studies”) literally treats performing cuteness as an academic subject in which Yuta ranks first. Here it is an affectionate, exaggerated way of saying that his precisely timed cute gesture is exceptionally good.
