f(x)'s Sulli and Ki Tae Young had a dramatic first meeting in the nurse's office as revealed by the latest still cuts of SBS's upcoming drama, 'To the Beautiful You'.

Filmed on July 21st at a set in Gwangju, the scene depicts Sulli visiting the nurse's office after fainting. Looking tired and completely out of it, it's easy for anyone to see that living life as an undercover girl in an all boys' high school isn't as easy as it sounds. The school's medical staff member, Ki Tae Young, is also seen thoroughly checking up on Sulli, perhaps suspicious and catching on to her secret. Sulli responds with a rigid stare, seemingly holding her breath.

This was actually the two's first time acting together on set following their script reading session. Staff admitted that an awkwardness hung in the air because they both spared their words, but once they got used to each other throughout the filming, they showed exceptional teamwork and completed their takes with perfection.

Sulli actually charmed everyone with her cuteness when she actually fell asleep while pretending to doze off on the office bed due to her killer schedule. Upon realizing her mistake, she got up immediately and apologized for falling asleep. Sulli made up for it by staying wide awake and alert for the rest of the cuts, as well as completing the filming without anymore NGs.

The drama begins airing on August 15th!
