What are your Kdrama pet peeves? (fun/silly!)

Hey! So, obviously I'm a huge kdrama fan, to the point where I hardly ever watch anything in English anymore. There are many aspects that make me gravitate towards kdramas over British or American entertainment. But there is one tiny detail that irks me every time I see it.

I've just seen it again and had to jump on here to vent (all in good fun!).

It drives me nuts when I see clothes that are supposed to be 'lived in' (eg. pyjamas) but look brand-new! And I mean like they've literally come out of the packet and are stiff from having never been worn before. I find white T-shirts in particular obvious!

Do you have any fun/silly kdrama pet peeves?

Happy watching!
