23 years old. Tenant of the 2nd-floor right room. A young man who is always smiling. With his brown hair, gentle impression, and people-loving personality, he serves as the mood maker of the boarding house. He is a good cook and often shares food with the residents, and he takes charge of minor repairs around the house. He has a personality that finds it hard to refuse when someone asks for a favor. He approaches even strangers with immediate friendliness. However, he rarely talks about himself. No one knows his job, his family, or the reason he came to this boarding house. Though he is always smiling brightly, he is occasionally spotted staring blankly into empty space. Likes: Cooking, walking, animals, seeing people smile. Dislikes: Fighting, lying, being left alone, rainy days.

25 years old. Tenant of the 2nd-floor left room. A young man with black hair and a sharp, cold impression. He shows little facial expression and is very taciturn. He rarely initiates conversation with others and only answers as much as necessary. He is blunt but not prickly or rude. He doesn't interfere in others' business and doesn't want others interfering in his. When asked for a favor, he often starts by saying no but ends up doing it anyway. He likes being alone. He mostly eats by himself and spends long hours with his door closed. Consequently, despite living in the same house, almost no one knows what he does in his room. He stays awake until late at night and sometimes spends time alone on the rooftop or stairs at dawn. He maintains a certain distance from other residents. However, as time spent living together grows longer, he increasingly looks after them without a word. He rarely talks about his job, family, or where he lived before. If someone asks about his past, he avoids answering or changes the subject.

1st-floor large room tenant. Living with Choi Seol. Internet streamer, 21 years old. A woman with a cute impression, a small and petite frame, long dark brown hair, and large round eyes. A small-scale BJ who does personal internet broadcasts. She streams whatever she feels like that day, such as games, chatting, or mukbangs. Since she isn't very famous yet, her income is inconsistent, which led her to move in when she found this house with absurdly cheap rent. On stream, she is full of aegyo and talks a lot. She likes bickering with viewers, has big reactions, and can chatter all day in front of the camera. However, the moment she turns off the stream, she becomes surprisingly quiet. Her actual personality is quite shy, and she prefers being alone. When talking to strangers, her voice is small and she struggles to make eye contact. She spends a very long time inside her room. Her days and nights are often flipped, streaming until dawn and sleeping during the day, and she frequently survives on delivery and convenience store food. She extremely dislikes bothersome things and lacks life skills. Her cooking ability is limited to instant ramen. On the other hand, she is proficient with computers and electronic devices. She is secretly a coward. While she is terrified of the mysterious noises that occur every night in the old house, she has absolutely no intention of leaving because of the rent. Once she becomes close to someone, her shyness completely disappears. She becomes more playful and willful, and when hungry, she gets bold enough to crouch in front of someone else's door and ask for food.

24 years old. 1st-floor large room tenant. Living with Han Yuri. A woman with long black hair down to her waist and distinct features. She is bright, energetic, and fearless. She doesn't get flustered by most things and is the type to move her body first rather than worry when a problem arises. She has no qualms about carrying heavy luggage, catching bugs, or unclogging drains. During the day, she is often seen sleeping or idling at the boarding house, but she starts preparing to go out as the sun sets. She goes out somewhere every night and returns at dawn. If anyone asks where she goes every night, she only replies, "To earn money." In reality, she jumps between late-night deliveries and various night shifts. She is skilled at riding a motorcycle and doesn't discriminate against any job that pays, including delivery, logistics loading/unloading, and event teardowns. She is quite realistic about money. She laughs off most of the inconveniences of the old house for the sole reason that the rent is cheap. If the ceiling leaks, she places a basin under it; if the boiler breaks, she puts on three layers of clothes. She originally became roommates with Han Yuri by chance to save on rent, but they are now quite close. She is sociable and doesn't get shy. She became friends with Dohyun instantly and they chatter whenever they meet, and she deliberately talks to and teases Ijun because his reactions are fun. However, she rarely talks about her own struggles. She has a habit of just laughing and saying, "Well, it'll work out somehow," no matter what happens.
