This was a long time ago. I can't believe it was back in 1999. Anyway, from memory...
Game Ruk Payabaad: Aom's mom owns a huge company. She has two daughters, Aom and her older sister. The two sisters are complete opposites and aren't that close. Aom is gentle, feminine, and lovable, owner of a flower shop. The older sister is fierce, loves danger, and sexy. Captain purposely enters their lives to avenge for his father, who was cheated by their mom that drove him to commit suicide. Captain has an uncle who is constantly feeding him with information and guiding his revenge. Captain saves the older sister from a speed chase on the road and she falls in love with him. He also gets hired by the mom to work at the company and gains her trust due to his capabilities and intelligence. As Captain plots and plans, calculating and manipulating each step with the mom and older sister, he by fate, meets an innocent girl who works at a flower shop that makes his heart beat for the first time. It has been years since he's felt like he was human being surrounded by hate and revenge. As he deepens in on his revenge, he falls more and more attached and in love with the flower girl. One day, at a company event, Captain and Aom are finally introduced to each other as the younger sister and the boyfriend of the older sister. Their love comes to a halt. As Aom tries to distant herself from Captain, his love only grows for her. Anyway, in the end, it was a misunderstanding, I believe. I think the uncle was the bad guy. Captain, who gains the company causes the mom to die. The older sister and Aom find out the truth, but it's too late. The older sister tries to get rid of Captain for the mom's death plus she's angry that Captain loves Aom and has never loved her. She shoots him a few times. She kills herself right after believing that he died. He survives and he enters monk hood. It's a sad ending. Lol Captain and Aom don't get each other but it was such a good lakorn. The acting was on point. The OST was superb too. The only thing is, Captain sleeps with the sister, so that's probably why they didn't make Captain and Aom end up with each other. The older sister hated Aom ever since they were kids. If they remake it, please ADD more skinship and sweet scenes between the leads. Lol This is a serious and real revenge story, so the leads don't end up together. It's realistic. I think all revenges that involve death or heartbreak shouldn't be happy.
Anyway, Captain sang one of the OST songs and the Beau sang the other. Ahh, both were such good songs and great lyrics.
