Han Mi-sun

She is half Chinese and half Korean, and has been a devoted friend to Yeong-ro ever since they met as children. A literary student, she is often seen as the “mother” of the group—constantly looking after everyone, making sure they’re safe, healthy, and truly okay.

Everyone, except Aki.

Because of his obsession with science, Aki has a habit of pointing out how illogical things are, which clashes heavily with her love for literature and fantasy. As someone who believes in imagination and storytelling, she often finds herself arguing with him, trying—and usually failing—to make him understand the beauty of things that don’t need to make sense. Their constant bickering has become a normal part of their dynamic.

She also loves sewing dresses and takes responsibility for caring for the plants in their room, especially since Addison keeps bringing more in. It’s something she does quietly, a reflection of her nurturing nature.

She moved to the city with Yeong-ro, leaving her home behind just to stay by her side. The two have been inseparable for years, attending the same schools from preschool all the way to college.

However, while she is strong for others, her own heart is less fortunate. When it comes to love, she struggles—often giving her all, only to end up heartbroken in the end.
