I think (if I remember) a couple of episodes, he exchange the shoes with some kid he found on the street just so he can look like he has issues with money (or something along the lines) and have Na Hae-soo have pity for him.
Taeha ask some random student to change shoes with him in earlier chaps. He want to wear cheap shoes to "impress" Na Haeso.
That's probably what Taeha's dad notices
He had to buy cheap shoes to court/look pitiful enough so he can get fl attention. I mean with all that money he's getting a cheap shoes for him would be yo thousand dollars shoes yet he have a 30$ worth shoes.... In da display like wottt.... Demnn bro(the bodyguard yall be simping
The tax bracket difference between that sneaker and the rest of those shiny shoes is enough clue knowing his son expensive taste lol.
My bad i mean he exchanged his expensive ass shoes to a cheap shoes to look pitiful yuhh
OMG I SEE I FORGOT DAT DAMN SCENEEEEE
THANKS Y'ALL FOR THE INFO OMG I HOPE BOTH TAEHA AND HAESOO TO BE SAFE
