Kim Minseok (a.k.a Xiumin) is in a very well known K-pop Idol Group called EXO as youve all heard of.  He is the trending member in EXO. He is also the mak-hyung and is very much loved by his dongsaengs. But, there is something everyone doesnt know about. Its a secret. Now, it shall be reaveled...Yoo SeoEun, or shall I say the late SeoEun, was a young and bright girl that was the girlfriend of young Minseok. She went through lots of terrible things in life and left the world 9 years ago.

Before reading this, I recommend you to read "Sentimental Romance" First. Its the story that is related to this one. Thank you^^For those of you who have read sentimental romance, you can roughly tell what happened right? HAha, yes, SeoEun is alive and she thinks that Minseok is dead. Understand? haha. Tell me if you want me to write a oneshot of how these two ends up finding out that they are both alive.
