Putri Indriani is a simple and smart girl who received a scholarship to enter Harapan High School, a favorite high school in Jakarta. She met SM*SH, a boy band that was on the rise and the sons of the richest families who were members of the TORO Group. On the first day of school orientation, Putri already had problems with SM*SH because she contradicted Rafael, the leader of SM*SH, which annoyed Rafael. This actually gives an idea for the other SM*SH members to challenge Rafael to conquer Putri's heart before the night of the inauguration.

After graduating from high school, SM*SH members who are now college students met Candy, a tomboy girl who liked to chew gum. She is a member of a band called "Bubble Gum", that did not like the arrival of SM*SH, due to the fact that they are part of the SM*SH hater community. Candy clashes with Rafael a lot. One time, Rafael suddenly stopped Bubble Gum's stage because he felt they were singing an insinuating song about him. From there, their relationship became increasingly heated.
