San And Yeonjun Reportedly Join G-dragon’s ‘good Day 2’

Lee So-ra also appears in the reported lineup, with the music-project show now expected to return to MBC in the first half of 2027.

G-Dragon’s “Good Day” could return with a combination of younger K-pop performers and established singers, according to a new casting report naming ATEEZ’s San, TOMORROW X TOGETHER’s Yeonjun and Lee So-ra among its participants.

Ilgan Sports reported that the second season, directed by Kim Tae-ho, is expected to air on MBC in the first half of 2027. The proposed lineup suggests a broader musical gathering around G-Dragon’s producer role, although the newly reported names and broadcast window should be distinguished from a fresh announcement by the broadcaster.

San, Yeonjun and Lee So-ra Lead the Casting Report

According to Ilgan Sports’ initial report, San, Yeonjun and Lee So-ra are joining the project. The outlet presents San and Yeonjun as performers who would bring a younger K-pop presence into a program built around collaboration across different backgrounds.

The interesting part of that combination is the space between their respective performance contexts. Rather than simply placing members of different groups on the same guest list, “Good Day” asks what happens when a producer brings participants together to make something that belongs to the project itself.

Our analysis is that the reported casting would make that creative process the central attraction. Viewers would have familiar artists to follow, but the program’s potential would depend on how their contributions interact, from developing musical ideas to deciding how a shared performance should feel.

A Later Report Adds More Names

An expanded Ilgan Sports report published later the same day also names singer-songwriter Kim Kwang-jin, John Park, Park Myung-soo, actor Lee Sung-kyung and comedians Lee Su-ji and Kim Won-hoon.

According to that update, the second season is expected to use a music-festival concept. The additional names widen the reported mix beyond idol performers, introducing people associated with songwriting, acting and comedy as well as singing.

A lineup report alone does not establish who will collaborate directly, which songs they might perform or whether every participant will have the same role. Those details would determine whether the program operates as one shared musical undertaking, several smaller collaborations or a combination of the two.

What Good Day Is Designed to Do

“Good Day” is a music-project program in which G-Dragon works as a producer with people from different fields to create a song that captures a year. According to TV Daily’s earlier report quoting production company TEO, G-Dragon’s participation in a second season was confirmed, while production timing and scheduling were initially undecided.

That format distinguishes the show from a conventional performance booking. A guest can become part of the development of the music, with rehearsals, conversations and creative decisions supplying material alongside the eventual stage.

It also creates room for a participant’s contribution to differ from the role viewers already know. An actor, comedian or singer need not approach a project in the same way, and the appeal lies partly in seeing how those differences are managed within a shared task.

The Broadcast Window Has Changed in Reporting

The latest first-half 2027 window comes after an earlier timetable discussed this spring. According to Ilgan Sports’ March report, TEO had said it was organizing schedules around a planned broadcast in the second half of 2026.

The November report therefore places the expected return later than that earlier plan. It does not provide a specific premiere date, and a reported half-year window should not be read as a completed broadcast schedule.

For now, the useful distinction is between the previously confirmed intention to produce another season and the latest reporting about who will participate and when it could reach viewers.

Another Setting for Cross-Generation Encounters

Readers recently saw San in a different senior-junior exchange through our coverage of his television appearance with BLACKPINK’s Jisoo. Our November comeback guide also follows ATEEZ and TXT’s group activities, providing context for the artists’ work outside this reported collaboration.

“Good Day” would bring those individual careers into a different setting, organized around G-Dragon’s production process rather than a group’s own release. If the reported lineup is announced officially, the next revealing details will be the musical assignments and how the festival concept shapes their collaboration.
