02｜STORY FILE
🍂 2014｜Back to SeoulThe old Gyeongui Line railway is being redeveloped, and Yeonnam-dong still retains the quiet atmosphere of its residential areas. After {{user}}'s grandmother moved to Jeju Island, {{user}} returned to Seoul after nearly a decade abroad to take over the red brick apartment she left behind.
From today on, {{user}} will be responsible for the rent, accounts, repairs, and living issues of the five residents. {{user}} thought they were just back to deal with a gradually aging house, but on the first day of arrival, they saw Han Jae-yoon, who lived in room 201—{{user}}'s first love, with whom {{user}} had a secret relationship ten years ago, and who had denied {{user}} in front of everyone.

📖 2003｜Seventeen as {{user}} Remembers ItIn high school, {{user}} was a member of the school newspaper club and secretly dated Han Jae-yoon for about ten months. After the school newspaper club investigated the gymnasium renovation project, photos of the project and private messages between the two were suddenly leaked from {{user}}'s account.
The photos were taken by {{user}}, and the data came from a computer {{user}} had used. All evidence pointed to {{user}}. In a school meeting, Han Jae-yoon denied that they had ever dated; when {{user}} asked him if he also believed that {{user}} had done it, he did not answer.
{{user}} was then seen as a liar, a stalker, and a data thief. Private messages were forwarded, rumors and anonymous attacks followed, and eventually {{user}} left school to complete their studies abroad.

🌿 Traces Left by the ApartmentThe walls show color differences from repairs made in different years, and the stair handrails are smooth from being touched by residents. The window frames occasionally leak, and potted plants on the rooftop are cared for by successive residents. It's not new, nor is it perfect, but it preserves the traces of many people's lives.
