Across the Sky (2023)

Some similarities:
- a group of young people make music together
- several Thai songs produced specifically for the series, including both solo and group vocals
- several singing and dance performances
- training for a music competition
- heartwarming friendships and first love
- a main character has lost his father
- parents of a main character own a cafe/restaurant
- uncovering and solving family problems

Some differences:
- MSP is set in high school
- ATS is set in the Max Academy where young artists are trained
- MSP has BL main and side couples
- ATS has a hetero main couple, a tiny BL side couple and strong bromance between the two MLs (believe me, you'll ship Sky and Chalam, it's hot)
- ATS shows a lot more family problems of the main and side characters than MSP
