Key fact #30

When f(Sulli) was in 6th grade, when neither groups have debuted yet, since Sulli was a sunbae trainee to Key, she came to him feeling a bit impatient and asked him, “oppa, since I’m your sunbae, can you go to the 3rd level and get my keys for me?”

(Key called this the evil side of Sulli.)
