Matthew Sato on High School Musical: The Musical - The Series (2023)

The Disney+ series High School Musical: The Musical - The Series returned for its fourth and final season, appropriately having the teen seniors preparing to put on a performance of the movie High School Musical 3, just as their school is invaded by filming for a High School Musical reunion movie. Episode 1 began with a scene from the reunion movie featuring several returning characters from the film franchise, including Ryan (played by Lucas Grabeel). The scene revealed that Ryan had a boyfriend in attendance at the reunion, played by Scott Hoying. The two shared a kiss. The scene also revealed a new high school couple as part of the plot. Matthew Sato played Mack, an actor playing one half of the couple. He later appeared shirtless as leading lady Gina crossed paths with her celebrity crush while he was getting measured for costumes. This caused some jealousy from Gina's boyfriend Ricky (played by Joshua Bassett). Joshua appeared in tanktops in multiple scenes.
