There's a time where you cannot even trust your closest sibblings. They're a burden but sometimes they are

more dangerous than you think. 

Jinyoung and his family invited his sibblings for a family meeting since they haven't seen each other for years.

He didn't know that through all these years, his cousin had a secret.

Will he be able to escape the threat he was about to encounter?

(this story has a bit of fan-service(ing), but overall i'll try to make a serious plot)
