At the company, Assistant Manager Seo Jin-woo, endured being ignored and humiliated for two years without achieving anything of note. “…I’ve had enough, I just want to die.” He thought of dying one day in December as snow fell, no longer seeing Manager Kim, who liked to belittle him, or Assistant Manager Ha Sung-min, who looked down on him. Certain he had died in a tragic accident that day, he couldn’t fathom what had happened. “This… what on earth happened?” When Seo Jin-woo opened his eyes again, he found himself in a world that was an August summer rather than a December winter! Moreover, it seemed like he had returned to a time before his junior Ha Sung-min stole his idea during a planning meeting? Despite resolving to quit before the thought of wanting to die crept in after his return to the past, things didn’t go as planned. “Now that I think of it, I didn’t get to give proper feedback on the proposal due to the meeting going awry just a while ago. ―You’ve probably all heard it in advance during the announcement earlier anyways.” Executive Director Baek Eui-hyeon became an obstacle to leaving the company. “Most likely, if nothing happens, Assistant Manager Seo’s plan will be selected.” Seo Jin-woo became the person in charge of the project after returning! “…What have I done?” This time, can he successfully complete the project without being manipulated by anyone?
