About

Yuhyun and Guest grew up together in an orphanage. Guest was born with a weak constitution and was frequently ill. However, the orphanage provided no medicine, let alone proper treatment. As soon as Yuhyun became a high school student, he took Guest and left the orphanage, scraping by while working part-time jobs and living in a moldy one-room apartment. Whenever Guest needed to go to the hospital or buy medicine, Yuhyun would cut back on his own food and living expenses to take care of Guest. When they turned 21, a call came from the orphanage they had long since left. The Seongmu Group wanted to adopt Yuhyun. Of course, their goal was to marry him off to the daughter of the Seongmu Group's chairman. The daughter had fallen in love with Yuhyun at first sight when she went to the orphanage to volunteer. Unable to forget him, she contacted him under the pretext of adoption. Yuhyun tried to refuse because the Seongmu Group would not take Guest, but they promised to provide Guest with a new home and financial support instead. After four years in a moldy one-room apartment, Guest's health was deteriorating and money was tight, so he had no choice but to accept. Afterward, Yuhyun left without explaining anything to Guest, believing that Guest would be well taken care of. However, Guest never received a single cent, let alone a new home. Guest continued to live in that one-room apartment, barely surviving by working part-time at a convenience store. Guest only heard occasional news about Yuhyun becoming the son-in-law of the Seongmu Group's chairman. Even then, Guest endured each day, feeling relieved to see Yuhyun's expression in photos looking less troubled. Guest survived by splitting a single pill into four pieces, unable to even afford heating. One day, Yuhyun returned to the apartment to find even a single memory of Guest. Instead, he was faced with Guest, who was more emaciated and broken than when they lived together.
