Four years ago, Khun Nueng ran away from her own wedding to Chet and moved out of her aristocratic household to live an ordinary life. Soon, 20-year-old high school student Anueng starts hanging around her, determined to win Khun Nueng’s heart. When Chet and Khun Nueng cross paths anew, Anueng is jealous and promises to become worthy of Khun Nueng’s love. Anueng often mentions running away and tries to come up with excuses to stay over at Khun Nueng’s condo. When Khun Nueng brings her home, she sees wounds from the abuse she faces at home.

Caught under the rain, Khun Nueng brings Anueng to her apartment. Aneung shares that she was born prematurely when her teen mother tried to abort her, which explains her poor health and why she hasn’t graduated yet. Anueng’s grandmother finds the portraits Nueng drew and burns them, assuming they were from a male admirer. Anueng mistakes Khun Nueng’s sister for her girlfriend and, to Nueng's discontent, gives up on pursuing her.

Sam advises Khun Nueng to clear up the misunderstanding with Anueng, suggesting she cares for her more than she cares to admit. After going three days without speaking, Nueng takes an opening to clear the air when she offers Anueng a portrait she drew of her from memory. Nueng begins opens herself up a bit to Anueng’s advances when Anueng’s grandmother discovers the true artist behind her portraits and forbids her from seeing her again.

Anueng’s mother Phiangfa blames Khun Nueng for Anueng’s near-death and Nueng feels terribly guilty. Chet happily learns that he is Anueng’s father. Phiangfa asks Nueng to help her become closer to her daughter so she’ll join her abroad and Nueng criticises her for neglect. Anueng is excited about going to an amusement park with Khun Nueng for her birthday but feels betrayed when she discovers her mother, Chet, and her classmate are all coming along.

Khun Nueng is tricked into having a meal with her own grandmother. Anueng convinces her mother to respect her wish to stay in Thailand as Nueng watches over her education. Nueng takes Anueng on a retreat and Anueng sneaks into her bed under the guise of not being able to sleep.

Khun Nueng sets stricter boundaries and her grandmother’s health begins to decline. When Phiangfa expresses concerns over Nueng and Anueng’s relationship, Nueng reassures her that Anueng would never fall for her. Anueng receives her entrance exam results which determine whether or not she gets to stay in Thailand and asks her father for a favour which she keeps secret from Nueng. As Anueng enters a new phase of her life, Nueng grows more possessive but also more and more aware of the need to let go. Grief-stricken, she takes one last opportunity to be cruel.
