Hormones

It's the start of a new school year. Popular student Kwan becomes class president, while bad boy Win challenges the school rules in a big way.

After playing guitar in one of Win's videos, Tar gets the chance to play with See Scape, the most popular rock band at school.

Kwan and Win are both chosen to represent their grade in the Teacher's Day ceremony. Sprite's flirtatious ways get her in trouble.

Phai loses his friends when he starts dating Sprite. The girls at school gossip about Tar and Toei. Mhog keeps neglecting his girlfriend.

Toei walks into her classroom to find the word "slut" scrawled on her desk. Tar wants to reach out to her, but things are still awkward between them.

Everyone is gossiping about Toei's run-in with the older girls. Thee and Tar get jealous when Toei starts hanging out with her ex-boyfriend again.

The students return from summer break. The kids, teachers and even parents are all talking about a steamy high school TV drama called "Love Struck."

Thee is hurt when he finds out Phu and Toei are together. Pop's younger sister is a big fan of See Scape, and she seems to really like Tar.

Now that he has a new girlfriend, Tar is walking on air. Toei feels uncomfortable when Mr. Pin, the handsome computer teacher, gives her attention.

Win re-enrolls in school, and he has a lot of apologies to make. Dao feels hurt when she sees Din, the boy she dated last year, with another girl.

Phu begs Toei to forgive him for insisting she stop hanging out with Tar. Later, Phu meets a bartender who introduces him to people he can relate to.

Win went to New York to better himself, but while there, he struggled to keep his demons at bay -- especially after meeting the hard-partying Jane.

Another school year begins. The girl who introduced Win to drugs in America transfers into the school, and she's shocked by how strict her teacher is.

Dao and Koi finally talk things out. Dao wants their close friendship back, but Koi wants more and is hurt that her feelings aren't returned.

Jane joins the band as drum major, but she has trouble with teamwork. Later, she sees Win out at a club for the first time since New York.
