tvN’s new drama “Showing Up Tomorrow Too” (내일도 출근!), adapted from the popular Kakao Webtoon of the same name, premiered June 22, 2026, reuniting actors Seo In-guk and Kang Mina for their third collaboration following the earlier hits “Bloodhounds” and “Twelve.”
The pairing carries built-in audience anticipation: Seo and Kang’s prior collaborations have each performed well enough to make their reunion a notable casting decision in its own right, independent of the source webtoon’s existing fanbase, giving the series two separate audience pipelines feeding into its premiere, webtoon readers who followed the original series and viewers drawn by the leads’ established on-screen chemistry.
The adaptation continues Korean television’s heavy reliance on webtoon source material for original programming, a pattern driven partly by the built-in audience such adaptations bring and partly by the pre-validation effect of a webtoon’s serialized reader engagement data, which gives producers a clearer sense of a story’s appeal before committing to a full production budget. Content Agency research has found webtoon-based dramas post viewership ratings roughly a third higher on average than non-webtoon originals, a track record that keeps studios returning to the format even as it raises concerns among some critics about originality in Korean television programming.
For tvN, a channel that has built a strong track record with genre-blending workplace comedies, “Showing Up Tomorrow Too” represents a relatively lower-risk bet: a proven webtoon IP paired with two leads whose chemistry has already been tested and validated by prior hits.
