So Ji Sub, who recently announced his relationship with Cho Eun Jung, has previously shown his good manners on numerous occasions.
So Ji Sub previously attended the press conference for the film, The Battleship Island, alongside child actress Kim Soo Ahn.
On this day, Kim Soo Ahn was dressed in an adorable white dress.
The dress, however, was apparently a little short and Kim Soo Ahn looked uncomfortable sitting in it. As soon as So Ji Sub noticed this, he did not hesitate to take the handkerchief from his pocket and hand it to her.
Thanks to So Ji Sub, Kim Soo Ahn was able to proceed with the conference comfortably without having to worry about her dress!
So Ji Sub also showed his good manners at another event for the drama, Oh My Venus. When co-star Shin Min A was trying to drink water, he silently took the bottle and opened it for her.
Meanwhile, Dispatch recently released photos of So Ji Sub and Cho Eun Jung out on a date and the couple confirmed their relationship shortly later. The two have overcome their 17-year age gap and have been dating for about one year.
