Oppa Lam Sing (Isan Melodies in Love)

In the past, Koon Kaen, a famous luk thung–mor lam troupe from Ban Nong Khun District, was constantly on tour. The troupe was owned by Grandpa Dui (Boonsong Nakphu) and featured its star singer Euy Fah Suyonghwa (Ying Thitikarn), known as the “Angel of Mor Lam.” She rose to fame with the hit song “Grab Ok Sai Ai Thi Hak” (“Embrace My Left Chest, My Love”), written by Damrong (Rung Suriya), Grandpa Dui’s son, who discovered and nurtured her career. The two also had a secret relationship, which resulted in Euy Fah becoming pregnant.
But driven by ambition, after giving birth to a son, Euy Fah decided to steal the lyrics to “Grab Ok Sai Ai Thi Hak” and run away with Winai (Nattanun Khunwat), the troupe’s manager, with whom she was also secretly involved. She left behind her newborn son with the Koon Kaen troupe. At that time, Atchara (Naruemon Pongsuphap), the troupe’s second singer, had only recently given birth to her own son and decided to raise Euy Fah and Damrong’s baby as well.
Twenty-five years later, Detchana (Thanakorn Sribanjong) and Tar (Akkharawat Jumnonwiwat), who has been sickly since childhood, grow up together in the once-famous Koon Kaen troupe. Grandpa Dui continues trying to keep the group alive by pushing Tar forward as the lead singer. The remaining musicians are Ta Ad (Wirachai Hatthakowit) and Odd (Thitipol Sawatsri), while Mayuree (Angkana Worratachai), the neighbor and childhood friend of Detchana and Tar, serves as the troupe’s manager.
Because the troupe no longer earns much, Detchana opens a coffee shop called Ma Lae Na to make extra income. Although Mayuree tries to persuade him to become another singer for the troupe, Detchana refuses.
Meanwhile, in Bangkok, Euy Fah — who fled and later opened her own music label — constantly clashes with Eknaree (Patchsita Athianantasak), the niece of Winai, whom they have raised unwillingly. Eknaree can sense their lack of sincerity, so she tries her best to take care of herself. In the present day, she works as a personal stylist for many celebrities. But just as her career and love life seem to be going well, she is suddenly shocked when her boyfriend Athorn (Phattharabut Khiannukun) is exposed for cheating on her and asks to break up.
Enraged, Eknaree posts a video of them on social media, but the woman Athorn was cheating with plays the victim, causing public opinion to turn against Eknaree. She is viciously attacked online, and both her career and romantic life collapse.
Mayuree, who was Eknaree’s close friend back in university, invites her to come recover at Ban Nong Khun and also asks her to help revamp Tar’s image. Tar had gotten into trouble with an influential person, causing no one to dare hire the Koon Kaen troupe anymore. But when Eknaree arrives, she is not welcomed by Detchana. The reason is that the woman Athorn cheated on Eknaree with — the one she posted online — is Dawan (Ploywarin Saenchai), the woman Detchana secretly likes.
However, once Detchana and Eknaree talk things through, they come to understand each other’s reasons. After that, Eknaree helps transform Detchana’s image and also makes the Ma Lae Na coffee shop more successful, bringing in enough money to pay off debts.
At first Tar does not believe in her methods, but he eventually agrees to follow her advice because he thinks that if Eknaree can make him famous, it might also catch the attention of Meya (Chotinapha Kaewcharoen), a high-society young woman and the owner of a garden restaurant, whom he secretly likes.
When Eknaree restyles Tar into an “oppa” image and creates a PR clip for him, he becomes famous. Euy Fah sees the clip and mistakenly believes Tar is her son, so she plans to recruit him as a new singer for her label. Then, when she sees Tar and Detchana, the two “brothers” of the Koon Kaen troupe, singing together on the same stage, she becomes confused. But once she is told that Detchana is the older brother, Euy Fah becomes convinced that Tar must be her biological son.
She then sends Pammy (Randapa Mantalumpa), a pretentious pretty girl who had once applied to be an artist in her label, to lure Tar away from the Koon Kaen troupe.
