Everyone is talking about the coworker but why did Haesoo have to make the situation weirder than it already is? When she called to tell TaeHa she gave him the wrong bag, instead of saying “please don’t open it, the contents are private” or EVEN “sorry I gave you my underwear instead haha!” it would have been WAY less awkward even if they did both have these thoughts/imagination. It’s just more realistic/reasonable than her treating TaeHa like he’s 5 instead of a full grown man who knows that underwear is a normal thing and that the mistake was completely unintentional
