A story of teenage love, music and relationships.

"Seasons Change" is about Pom (Withawas Singhalampong), a high school boy who has a great interest in rock music, and also a great talent for the drums. After his final exams, on the first day of summer, Pom follows Dao (Yuvanat Arayanimitsakul), the girl he is attracted to, to Mahidol College, Thailand's only music school in Salaya. This decision is made behind his parents' backs.

Dao is very popular amongst her peers and everyone else in the school for being smart, beautiful, kind-hearted and gifted in playing the violin. She wants to study at Mahidol College because she is music oriented, but Pom only enrolled to be next to her.

Pom is actually only good with the drums when he is playing rock. However, when he realises that Dao has joined the orchestra, he decides to join too, and gives up the drums for the timpani. After getting into the orchestra, he finds himself drenched with a torrent of difficulties. Even with the help of his lecturer, Professor Jitaro (Kazuki Yano), he does not improve and realises that his talents in drumming can't help him in the least when it comes to playing the timpani.

Along the way, Pom meets Aom (Chutima Teepanart), who is the daughter of his father's high-school friend. A bond starts between them and soon, they hang out a lot together. Aom also influences Pom to appreciate classical music.

When Pom gets accepted for a scholarship in Hungary along with Dao, he realises that the season of love between Dao and him seems to have come to an end. Will he still accept the scholarship? Or will he stay in the orchestra?

This is a simple love story which all teenagers can relate to, or even anyone else who has been a teenager before. The friendships, the fleetingness of puppy love, and the relationship between parents and child, are all brought up in "Seasons Change".

The friendship between Pom and Aom, and also with Chat and Chid, played by Chalermpol Tunthawisut and Ruchchu Surajarus respectively, makes the movie fun to watch. Their dialogues, and the bond they share, tickles you with a warm feeling. Showcasing the lighter side from the older generation is Yano's Professor Jitaro who is the movie's main comic relief.

The classical music, "The Four Seasons" by Antonio Vivaldi performed by the orchestra in the movie, is soothing and blends perfectly into the romance of this movie. In contrast with the lilting strings of "The Four Seasons" is Pom's furious rhythm at the drums, adding a driving cadence to an otherwise sweet and simple movie about teenage romance.
