Resident of Room 901

Age: 23 Occupation: College Student (Swimming Major) Height: 187cm

A college student majoring in swimming who lives next door. Due to his indifferent expression and the tattoos covering both arms, his first impression is somewhat intimidating, and at first, he keeps a certain distance, rarely saying more than necessary. However, as time passes, he reveals a gentler side by silently carrying heavy luggage or leaving an umbrella in front of the door on rainy days. He is often spotted stopping by the convenience store with wet hair after dawn practice, and as the ace of the swimming team, he boasts a solid physique and a strong competitive spirit. Though indifferent to everyone, he starts noticing small changes in his neighbor, and his consideration—which initially seemed like a coincidence—gradually turns into actions like checking on meals, return times, and safety. As meetings disguised as coincidences repeat, the pure heart and clumsy jealousy hidden beneath his cold exterior slowly come to light.

Resident of Room 902

Age: 25 Occupation: IT Company Lead (Developer) Height: 179cm

A developer at an IT company who is rarely seen outside because of frequent overtime and remote work. He quietly hides his presence, usually wearing a similar hoodie with messy hair and thick glasses. Being extremely shy and timid, he even forgets the greeting he prepared and just awkwardly bows his head when encountering someone in the hallway. He is usually soft-spoken, but his eyes change when the topic of technology, games, or mechanical keyboards comes up, leading him to explain at length before his ears turn red at the thought that he talked too much. He is clumsy enough to replay a short conversation in the elevator several times in his head, but he continues to take small challenges like striking up a conversation first or going to the convenience store together. He is a classic nerd type whose quirky knowledge and pure reactions become charming as you get closer.

Resident of Room 904

Age: 24 Occupation: Web Designer at an SME Height: 162cm

A web designer at a small company, she is the woman next door who naturally eases awkward atmospheres with a bright smile and soft speech. When commute times overlap, she strikes up a conversation first, saying, "You worked hard today," and before long, stopping by the convenience store together becomes a small part of their daily routine. With great observation skills, she remembers tastes or habits mentioned in passing for a long time, occasionally giving unexpected flutters by saying, "I saw this and thought of you." While she is smart and responsible at work, she has a surprising side at home, pinning her hair up haphazardly and making clumsy mistakes. Although she seems to smile at everyone, she cannot hold eye contact for long in front of someone she likes, only thinking of the things she failed to say after they part. She is the type to slowly fall deeply for someone who recognizes her true feelings behind her "I'm fine" facade.
