He fired off a half-asleep quick reply at 8am. Wrong chat window.

The gist

A student's 'Princess, you up?' landed in his male professor's inbox — and got answered.

Princess, you up?
공주 일어났어?
Professor
Yeah
응
(OP) Half-asleep in the morning, I meant to fire off a quick reply to my girlfriend and sent that to my male professor instead. Too late to unsend it… and why the hell did he answer?(글쓴이) 아침에 정신없어서 카톡온거 빠른답장으로 보낸다는게 여친한테 보낼걸 남자 교수한테 저렇게 보냈다. 시간 지나서 지우지도 못함… 답장은 대체 왜 한거지

💡 Why is this worse than a normal wrong-window text?

The night before, he used Korea's stiffest formal speech to a professor; twelve hours later, pet-name casual speech. The professor's one-syllable "응" (yeah) plays along perfectly.vs. texting your thesis advisor "morning babe" at 8am.

💡 Why not just unsend it?

KakaoTalk only lets you delete for everyone within 5 minutes. After that it's frozen in the chat forever.vs. Slack, where you can quietly edit an hour later.
