Sister, will you kiss me?

9 years ago...

(But the two of them are destined to never meet again...)

Required Station: Oh my...there's a fire!!! What should I do, call the police!!!

9 years ago Kim Yeo-ju: I'm relieved... (crying) Beomgyu... Beomgyu... hey...

(That's how the two of them ended up apart... I was so sad that I quickly forgot about it.)
