SuckSeed: Huay Khan Thep (2011)

Ped (Jirayu La-ongmanee) was a shy boy who had never listened to music until introduced to the world of Pop and Rock by would-be childhood crush Ern (Nattasha Nualjam). Ern soon left for Bangkok, however, and it is six years later in their final school year when she is re-introduced to Ped and his brash best friend Koong (Pachara Chirathivat). Koong convinces Ped, along with schoolmate Ex (Thawat Pornrattanaprasert), to form a band, partly to be cool and attract girls, partly as an attempt by Koong to try and one-up his popular twin brother Kay.
