Seven credits, not the single 2026 web drama his name usually turns up attached to. The shape of the seven tells you something a single credit could not: this is a working Korean short-form actor with a four-year run behind him.

He has credits in both girls’ love and boys’ love, which is rare. Three of Us (2022) is a polyamorous story tagged girls’ love; everything from 2024 onward is BL. Actors in the Korean queer short-form sector are usually sorted into one lane and stay there, and the crossover is worth recording.

SUKFILM twice. Wrong Number in 2025 and Backdoor in 2026 are both SUKFILM productions. That repeat is the whole visible mechanism of a career in this part of the industry: no agency announcement, no casting news, just a small production company that calls the same actor back. The same pattern shows up elsewhere in this database on Korean profiles tied to Flying Penguin and on Filipino ones tied to Oxin Films. It is how the short-form sector actually works, and it is invisible unless you read a filmography properly.

Two things checked here and recorded rather than smoothed over. First, the identity trap: several different people share the name 정재빈, including a footballer, a comedian and a violinist. Everything on this page is pinned to a single database person record verified through the Backdoor character credit, and a Korean-language reference entry independently matched both the birth year and that same credit. A separate acting profile found on a Korean industry site could not be matched to this person, because it carries no Backdoor credit, and was therefore not used at all. Second, an episode count discrepancy: his Backdoor credit is recorded against twelve episodes while the series record itself lists five. That has not been reconciled, and guessing which figure is right would be worse than saying so.
