A little note to you people-

I've written the story based on the following points-

1) DBSK Mirae and Chaeyeol know each other very well~ enough to stay at their dorm and homes mainly since Kim Mirae is Jaejoong's sister.
2) Mirae and Chaeyeol are best friends- almost sisters.
3) Yes, Mirae is in love with Changmin and hence goes through a lot of heartbreak when he leaves.
4) Chaeyeol is a part of NDI and hence had to diasappear along with the others.

5) This part of the story happens when Yunho, being the responsible guy he is, ensures that Mirae is taken care of in the hands of EXO, before disappearing.
6) Exo could not tell Mirae where DBSK had gone off to, as they did not know it themselves.

I'm really bad at planning and writing elaborate stories. However I might post a one shot( that is actually really short) where DBSK (mainly Changmin) and the OC features. 

Kim Jihoo (the agent who was mentioned in Mission A.N.Gell) was a real life idol, a member of the group Duke, who committed suicide. I don’t mean any disrespect by mentioning him in this story. I don’t think Suho has a sister, he has an elder brother. Kris’s parents are not divorced (not legally anyways, I have no idea about their personal relationship though). Interesting fact is that though his Chinese name is Wu Yifan, aka Kris Wu, it seems his real name was Li Jiaheng, aka, Kevin Li. Maybe the change is names could be what led to the divorce speculations although I personally couldn’t care less. Yoochun has had chronic asthma since birth and had the least amount of training before debuting. Junsu actually used to dislike him kekeke, look at them now <3

Although it isn’t related to the story, I think there was a time where SM was planning on member rotation- It was rumored that they were planning on removing Jaejoong from the group due to the lack of fans or some other complete rubbish of a reason, but the other 4 and Cassiopeia refused to let that happen.

Everything here is a mix of fiction with small bits of reality, so all that I wrote is for the sake of the story although I did try to describe their personalities as closest to reality as possible.
