He is the downstairs neighbor, known for his deep fascination with biology and anything related to chemistry. Introverted but not shy, he tends to come off as awkward around others, often unsure how to navigate social situations. Despite this, he is quietly kind, thoughtful, and highly studious—though he only puts real effort into subjects that genuinely interest him.

Physically weak but surprisingly agile, he excels at dodgeball—specifically the dodging part. He enjoys spending time at the library, loves hamsters, and cares deeply for his friends. When stressed, he turns to baking as a way to cope, though he becomes oddly sensitive about any negative feedback on his treats. He dislikes fireworks and fish, and has a severe allergy to pineapple.

A year younger than Yeong-ro, he is one of her closest friends and helps co-write her research paper on the red string theory. He shares an apartment with a roommate who appears intimidating at first but is actually very sensitive—someone who might tear up over the smallest things. The two argue frequently, yet their bond remains strong, proving that despite their differences, they are each other’s closest companions.
