People talk about Kwon Ihyeok and Hyeseong. The two must have been married in a past life. For 6 years, until the gangster became a respectable company CEO, Hyeseong was always by Ihyeok’s side. They were perfect partners. Until Hyeseong dropped a bombshell.“I’m going to become a farmer.”Hyeseong abruptly announced his resignation and left Ihyeok’s side.“Hyeseong. I can’t let you go.”But Ihyeok, unwilling to easily let him go, begins actively investigating the reason for Hyeseong’s departure.“Sir, by any chance…are you living next door to me?”“Yes.”There must be some scumbag who lured Hyeseong to a place like this.
