It's a story of two friends. One of them is Kai (aka Jong In) and he holds responsibility to keep her safe. He has walways been with her. Been by her side. Cared for her. Even loves her but when he tries to help solve a problem that's been ongoing and is getting serious, it gets difficult. 

Author's Note:

Seriously, one day, I might just take up a class on how to write descriptions...

Originally, I had wanted to put the title as Baby, Don't Cry as in the song but Inseparable seemed to have had a much better fit. It's based on EXO-K's Baby Don't Cry though. 

You can use it as a soundtrack... ;)
