My best friend said she was just protecting me from bad men. So every time I started dating someone new, she would turn herself into his dream girl. She'd flirt, chase him, and seduce him until she ended up in his bed. And every time, she'd send me the photos. Always with the same cheerful caption: "Bestie! If I hadn't tested him, you'd be heartbroken again. Aren't I good to you?" I was tortured, broken, humiliated. Eventually, I cut her off completely and moved to another city. Then I met the man I thought was my true love—Liam. He was kind, devoted, and loving. I thought I could finally be happy. On my wedding day, I found Madison standing in my dressing room, disguised as my makeup artist. She smiled at me, just like she used to. "Don't worry, bestie," she whispered. "Let me test this one for you. Then you can marry him." She drugged me, then put on my wedding gown and got into bed with Liam. But I woke up in time. I burst into the room with our families. I caught them together. Later, I got pregnant. During labor, I hemorrhaged. Liam watched me bleed and refused to sign the emergency consent form. "Madison just wanted to give herself to me before our wedding—to fulfill her wish," he said coldly. "You humiliated her. You drove her to suicide. She died carrying my child." "You and the bastard in your belly deserve to die too." That was when I realized—the man I loved had already fallen for my best friend. I died in agony. My ashes were thrown into a ditch. Then I opened my eyes. I was back. On my wedding day. And Madison was standing right in front of me, pretending to be my makeup artist.

They are BESTFRIENDS. Not childhood best friends. They met when she was 12 and he, 13 and they had stuck close to each other since then. Joan, that was her name and her best friend, King. Now she was 17, he, 18 and it seemed like everything stood against their five year friendship. Joan’s mother’s dislike for King, the long distance from King’s home to Joan’s, their separate schooling and the fact that King was basically non-existent. And then even more bigger obstructions come into play. Koty, the handsome football jock that is unrelentless in his effort to make Joan his; Joan’s unknown father and King, the new feelings he had started developing for his best friend. They have to struggle to keep their best friendship blooming despite all their problems but the tempests are too strong; the storm too overwhelming and then the final test… Who will betray who?...

On the day of the company's annual gala, I quit my job and went back to the countryside, using up all my savings to help my best friend raise her daughter. She had died tragically, swept away by the river while trying to retrieve my hundred-million-dollar gala prize ticket that had fallen into the water. Wracked with guilt, I honored her dying wish and married her husband. After the wedding, I sold my blood and even a kidney just to make ends meet, raising my stepdaughter with everything I had. Eventually, she fulfilled her dream of winning the Best Actress Award and was about to marry the richest man in the country. But just as I was preparing to give a speech at her wedding, I saw my best friend, who had been dead for over a decade. She clutched my stepdaughter's hand and accused me of being a homewrecker who seduced her husband, and even claimed I had been the one who pushed her into the river all those years ago. Only then did I learn the truth—she had faked her death all those years ago, just to steal my prize ticket and travel the world, leaving me behind to raise her family. The shock sent me into a cerebral hemorrhage. When I opened my eyes again, I had gone back to the day she drowned.

My best friend, Scarlett Throne, is diagnosed with cancer. After running away from home, she takes her own life. She leaves behind only a testament and a pair of eight-year-old twins, a boy and a girl. "You're the only person I can rely on in this world. I'm not asking you to adopt them, but just make sure they have enough to eat." Out of compassion, I take the siblings in. For the next 20 years, my husband and I have been working hard together to raise them, buying them cars and houses. But one day, my adopted daughter reports my husband for being abusive toward her. Even my supposedly dead best friend suddenly appears and testifies against him. I demand to know why she does such a thing. My best friend, filled with righteous indignation, says, "I see you as my best friend! I've never thought you adopted my children just to serve your husband's perversions!" My husband's reputation is ruined, and he's been thrown in jail. I desperately try to prove his innocence, only to be forcibly sent to a mental hospital by my adopted son. There, I wither away and die. When I open my eyes again, I find myself back on the very day my best friend was diagnosed with cancer.
