Possessive love isn't always soft. Sometimes, it claws, controls-and aches. Lookmhee has always been by Sonya's side, ever since they were little girls playing in the schoolyard. Protective to a fault, possessive without understanding why-Lookmhee saw Sonya as hers. Not to share. Not to lose. As they grow up, Sonya begins to crave freedom, friendships, and a world beyond Lookmhee's intense gaze. But Lookmhee isn't ready to let go. Not now. Not ever. In a tangled story of childhood bonds turning into dangerous devotion, Only Mine explores the fine line between love and control-and whether something broken can still become something real.

Blackwood Academy, a very prestigious school that is very well known in high society. Sonya Saranphat is a queen bee, and Lookmhee is a nobody, until an arranged marriage forces them together. Neither wants this, but as they play the perfect couple, buried secrets about their families start to unravel. The deeper they dig, the more dangerous the truth becomes. Will they remain enemies bound by a silent contract, or will the truth bring them together before it's too late?

This Fan Fiction will have 4 seasons. High School, College, New Adult, and Adult Life. A new chapter will be released everyday, but each chapter will be no longer than 2K words. The story begins when Wan Viva and Khun Pleng are in their final year of high school and their story will continue until they reach adulthood and have their own jobs. This fanfic will tell a story about: what if Khun Pleng's father did not commit suicide, her mother did not die of a heart attack, and her family did not have financial problems, Wan Viva's mother is not a cruel mom? ------- The story follows two childhood best friends, Khun Pleng and Wan Viva, who have grown up together and navigated their senior year of high school side by side. Khun Pleng comes from a wealthy family, while Wan Viva's mother works for Khun Pleng's family. Despite their different social standings, they have always been close, supporting each other through every challenge. However, their friendship becomes strained when both develop deeper, more complex feelings for each other, complicated by jealousy and unspoken emotions. After a period of tension, the two reconcile, realizing they are still deeply connected. They both perform well in their high school exams and plan to attend the same prestigious university, where they decide to continue living together. As they prepare for university, the girls reflect on their bond, acknowledging that their connection goes beyond friendship, and they look forward to facing their futures together.

The story begins thirteen years after Khun Pleng walked away from Wan Viva. Time has passed, but the feelings remain-complicated, unresolved, and deeply buried. Wan Viva has locked her heart away, refusing to let anyone in. Meanwhile, Khun Pleng has found herself entangled with someone new: Ingfa, a stunning and beloved actress (adapted from Secret of Us). But love is never simple. Especially when the past refuses to stay in the past. Khun Neung (adapted from Blank) also enters the picture, adding another layer to an already tangled web of emotions and history. The tables have turned. Wan Viva tries to suppress the feelings she once held for the girl who left her behind. But Khun Pleng can't ignore the guilt that still follows her every step. She knows the pain she caused-and she knows she might be too late. Will Wan Viva find the courage to open her heart to the one who broke it? And will Khun Pleng choose the difficult road of redemption and fight for her first love-rather than surrendering to the comfort of a near-perfect new romance? A story of heartbreak, healing, and the second chances we don't always believe we deserve.
