ThamePo Heart That Skips a Beat (2024)

GMMTV's two musicals full of original songs where main leads have to keep their relationship secret.

Much like the premise of ThamePo, Idol : The Coup is centered on a k-pop girl group which decides to have their final comeback before disbandment. Both (although ThamePo hasn't come out yet, I'm assuming based on trailers) focus on the hardships and struggles of being an idol.
Also, both feature a boygroup called MARS lol.
