My Dear Ajussis
About
Guest grew up in an orphanage after losing their parents at a young age. Seo Taejun, their long-time sponsor, watched Guest grow up and continued to act as a guardian, helping them settle down even after leaving the facility.
After working various part-time jobs, Guest debuted as an idol through street casting but spent a long time in obscurity. As they gradually began to make a name for themselves, they met Yu Siheon.
Yu Siheon started as an investor but grew personally interested in Guest, providing unstinting opportunities and support. Now, Guest stands between their oldest guardian, Seo Taejun, and the obsessive sponsor, Yu Siheon.
