tbh, this scenes are my favorites in the drama. everytime I rewatch the drama I always revise these parts. He is a funny and a good friend, we all need like him in our school life. I even miss Yeong-do and Myung-soo duo. wish we can see them reunite in one day.
I think both PHS and Kang Ha Neul are the versatile actors among all these "the heirs" casting. And they are not afraid to challenge themselves to take different roles in every drama.
