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. Ihyeok is convinced, and even does background checks to uncover Hyeseong’s secret, but he is missing a very important point.“Strange. Why do you smell so sweet?”>> A Taste“How much have you been drinking?”“I don’t know. As much as was given to me?”Ihyeok’s voice seemed normal, but Hyeseong knew.

Why do you smell so sweet?”‘Could it be…my pheromones are starting to flow?’That was not a good sign at all.“Sir. Step back for a bit.”Then, out of nowhere, Ihyeok pressed his lips to Hyeseong’s neck. A tingling sensation began burning through his body.“Sir, wait…ah…”Ihyeok, who had been brushing his lips against him, slowly started licking and sucking his neck.
