Today, the following fanaccount was posted on Korean web:
Today it seemed that a few Japanese ladies who seemed to be fans of Muwon, around ten of them maybe, came to the set.
They were holding small notebooks and such, but
Mr. Park Youngkyu-nim (T/N: the actor who plays Chairman Cha) himself went over to them first and
Said to them one word—“Sign.” Lolololol
He meant that he’d sign his autographs for them.
As he did so, he asked the fans’ names too lolol. It seemed that he was writing the names of those fans as he gave them his autograph.
So cute keke
LOL Chairman Cha! Here is a cute clip from the episode 06 of Protect the Boss. Chairman Cha is doing community service XD ^_^;;;;

Lol .. He’s cute asking for their names and stuff. I wouldn’t mind getting his autograph but still I want jaejoong’s xD ..
indeed the prince of japan has fans everywhere
so although he’s in real life but his role as chairman who always do community services still stick in him ohohohohoh
He’s so cute. lol Actually if his character wouldn’t shout all the time I would like it more. I wonder what face he put on when he said that to them.
ahaha:) Pak young Kyu is an amazing person! On Thursday, I had visitied the set with my friends. He was so carismatic that I could not say anything except “Hello.” in Korean. Later, my friend asked for his sign and he signed each one all of us. When he learned that we were from Turkey he was excited to hear it. Then I said ” Because of your character I could not speak to you first. I was shy.” and he replied “Oh thank you, thank you.”. And I’m pretty sure that he will visit Turkey..:) He is an amazing person. So carismatic and kind-hearted!!
Awesome, you lucky girl…
remember in the beginning of PtB filming, Jae had said that he was too happy and everybody was suppotive towards him. I also talked to director and let him know that many people all around the world tries to translate the drama into their owns language right after episode has been aired. he was so kind towards us. actors, staff, director… everyone works really hard and there is a great cheistry between them. then I realized that Jae was not sayin é I am happy.” just to us to make us happy. He is happy working with them! And thanks to them I had a few tear drops while leaving the set.. Everyone in set makes the perfect PtB. And Jae.. You can feel the athmosphere there. His inner world must be relaxing while working with them. Sorry, I am a bit emotional these days.
awww, thanks for sharing this account!
Özlem Altıntaş (@chuchi24) Hi, thank you for your fan-account. May I ask you something in private? My e-mail is zoniz_murasaki@yahoo.com.
Thanks for the fanaccount, it’s hearthwarming …. ^^
you’re welcome^^ it’s my pleasure to share.
@murasaki: sure you can. I’ll mail you.
Everything was awesome and I am one of the lucky girls that could get sign!! When we are first there we said hello to him nervously and he answered our greeting by bowing his head a little and we were determined to approach him even though we were also a little bit hesitating… I approached him with a pen and notebook saying could you please… sign? He was shocked I think he didn’t expect it he repeated in an amused manner “Sign?” and I said yes he took the pen and notebook from me and talked to us like my friend said and he was really happy to meet us T.T I think that’s why he asked Japanese fans for sign after us… I am really happy to see this account it shows that he liked us T.T
