Por favor Regrese, Señor

Without knowing the reason behind their deaths, Young Soo and Gi Tak find themselves in the afterlife! Before dying, Young Soo leaves his wedding anniversary celebration and faces an unexpected crisis because of a suspicious rice cake package Da Hye received at the funeral of his boss' relative. Meanwhile, Gi Tak, who had peacefully been running a pub with his mob family, suffers an irreversible accident while carrying out the request of Yi Yeon, who suddenly sought him out.

Two days after the next heaven-bound train, the time granted in this world is two months! Young Soo, excited to have returned as a handsome man with the perfect, muscular body he always dreamed of, and Gi Tak, in deep despair, having returned contrastingly as a beautiful woman with a high voice and slender body type. The two who must live as Hae Joon and Hong Nan for two months each make their way to their workplace and learn surprising truths hidden after their deaths. Meanwhile, Maya, having become anxious due to Young Soo's return error, hides the real Lee Hae Joon's identity and uses her last resort.

Hae Joon and Hong Nan are drinking at the same cart bar, swallowing their pain which they can speak of to no one! Hong Nan, unable to bear the sight of Hae Joon crying while drunkenly spouting nonsense, offers tough comfort with a glass of soju, and Hae Joon feels a degree of familiarity. Meanwhile, the real Hae Joon, having arrived in Japan by Maya's piloting as a last resort, buys a ticket bound for Korea from a suspicious broker.

Yi Yeon, in peril by Suk Chul, threatening her with all manner of underhanded methods! An upset Hong Nan, who appeared anxious at the sight of Yi Yeon throwing a liquor bottle, shouting at her to leave, and after entrapping Hae Joon and drunkenly spouting nonsense, ends up spending the night at Hae Joon's home. Meanwhile, Hae Joon, to free himself of false charges against him, call Cha Jae Kook and the directors to the department store's main conference room.

Hong Nan is leery of the sudden offer of a leading role by Director Gu, who produced Yi Yeon's debut drama, to Yi Yeon, who was without work through Sunjin Group's interfering. Hae Joon, in ill spirits after learning that Da Hye met Ji Hoon separately at Knulp Pub, because of words he blurted out unconsciously on the day of rehearsal of Ji Hoon's 2016 S/S luxury fashion show, ends up in charge of the show.

Hae Joon, at the sight of Da Hye in hot water, kneeling in front of a customer being investigated in the department store, having lost his sanity! Hae Joon, bound to break all taboos in front of a crowd of onlookers, narrowly averts the crisis thanks to Hong Nan's war-like iron curtain. Meanwhile, Yi Yeon, who feels Gi Tak's absence at his rooftop apartment, sobs chokingly, while Hong Nan can only watch from the doorway.
