The actress in 'Catch me if you can updated her blog. 

“I’m not that familiar with KEY-sshi, and because I only have a small role, we’ve never really talked. On the second day of the rehearsal, I had terrible cramps from my period, and during break time, I crouched down in a corner clutching my stomach, it was really painful then. The pain was really unbearable, and then suddenly, a hand tapped my shoulder. I raised my head to see KEY-ssi, but before I can even react to my surprise, he handed me a pack of chocolate without a word, smiled at me and walked away. I was really touched! KEY-ssi sent me warmth and care when I most needed it! And from then on, I became a SHINee fan!!”
