It’s the SHOE😭😭

Omg I don't understand. Hoooow?

cuz taeha got cheap shoes to seem poor to na haeso

I think the others shoes were fancy and made for suits/business.

So compared to a pair of sneakers it seems out of place.

Oh, yes! I remember the pair of shoes he exchanged with a student to make his shoes look cheap for Na Hae Soo.
