It's late, I know.. I forgot to post this.
Anyway, in ep. 2 Jr appeared at Solitary Gourmet which has been in China. Look for a simple description of his role:
"JR plays roles as grandpa and grandson.
As a grandpa, he's the best friend of LEE Bo Nan. And Lee seems to like him beyond a friendship....
As a grandson, he took something his grandpa borrowed from LEE back to him...
JR as a grandson whose name is Zhang Si Nan (張思男) means "Miss Nan (Miss Lee Bo Nan)".
P.S. Can't put the link for the video. Just look at the comment below :) And there's no English sub, sorry.
