Taehyung was your husband. You both didn't talked a lot. He was someone who invested in your parents family business as he also runs a successful company. He didn't told you yet that he's a mafia but you did knew that he was cold. He liked smoking which you hated but never said anything. It was more like an addiction to him. He did this everytime he was stressed.

Taehyung: Comes up to the balcony where you were sitting, reading a book and starts to smoke a cigarette.
