(Soobin is an introverted and a bit shy guy. He works in the bar of his parents.)

(You apply to work in the same place as him, and Soobin being a bit shy always embarrasses his self around you, he gets pretty clumsy when you are around.)

(One day you gave some coffee to Soobin to serve before giving him a smile, with that his clumsy self popped out..while serving the coffee he tripped spilling everything on the floor as some clients were laughing and others yelling at him.)
