My Forever Sunshine

Paeng often acts up and gets into trouble due to her parents not having the time and attention for her and only shower her with materialistic gifts. Her father, Tharathep, enlists Artit to look after her while he is busy. Artit is the son of his friend, Krongprateep, who owns a farm in the country. However, Krongprateep's shareholder, Songtham, conned him and insisted that he pays off the debt by handing over the farm. Tharathep offers to help Krongprateep and lends him money.

Tharathep suddenly appears at the school and brings Paeng to Sunshine Farm, saying that she has to stay there for a while as he and Pimnapa deal with some problem. Paeng is not happy with the arrangement and escapes to her home in Bangkok. However, she hears a gunshot and goes to investigate. She finds a lifeless Tharathep on the floor with a gunshot to his head. Pimnapa has also died. Artit tries to cheer Paeng up by letting her plants some flowers and entrust them in her care. Rumors about Paeng marrying Artit starts going around and Tubtim tries to put a stop to it.

Paeng goes to school and gets into a fight with Nang when the latter insults her for being an orphan. Krongprateep reveals to Tubtim that before Tharathep's death, his final request is to have Paeng engage to Artit in fear that she might end up with someone horrible in the future. Jaem and Aueng suggest to Paeng that they should go back to Bangkok but Paeng has flashbacks to Tharathep's death, resulting in a mental breakdown. Artit decides to tell Paeng that he doesn't love her. He was being kind because he feels sorry for her and that she actually loves him as a brother. But Paeng proves her love by kissing him instead.

Paeng gets into a fight with Nang again and as a result a big fight also breaks out between her and Tubtim. Artit starts giving Paeng the cold shoulder and is straight up cruel to her when she's in his presence. In his attempt to help Artit keep Paeng at bay, Korakot inadvertently escalates the problem when he decides to send Paeng a picture of Artit and Ling. Paeng goes to see Artit at his university in Bangkok and chaos ensues with Ling being roped in in the process.

Paeng put laxatives into the food that Thongkhum and Duang prepared in hopes of getting them fired but ends up poisoning all the farmhands. She then runs away when being confronted and comes home feverish, so Artit begrudgingly takes her to the hospital. She later escapes back home and finds Artit drunk in his bedroom. Paeng tries to assault him but he manages to pin her down. However, Krongprateep and Tubtim come in amidst the struggle and Paeng frames Artit for trying to rape her. Artit becomes angry that Krongprateep will not believe him and drives away. On the way, he crashes his car and is rendered paraplegic. Paeng confesses to Krongprateep and he suggests that she continues her study in Bangkok instead. Six years go by and Paeng graduates from university.

Paeng returns to Sunshine Farm to learn the ropes since Krongprateep doesn't allow her to run her own farm just yet. As Paeng expected, almost everyone at the farm still treats her with animosity. Artit is especially the most antagonistic by insulting her, making her work non-stop and starving her. Paeng decides to stay to prove that she's changed for the better and to atone for what she's done in the past.
