It's a love story between the disobedient student Kang-wook and his teacher Yool-ju set in a high school in Chuncheon.
Before meeting Kang-wook, Yool-ju has been dating Tae-hyeon, a public prosecutor. But over time Yool-ju and Kang-wook fall deeply in love with each other despite social prejudices, the age gap and the teacher-student relation. One day, Yool-ju accidentally kills Kang-wook's classmate who intentionally harasses Kang-wook. But due to narcolepsy, Yool-ju doesn't remember what has happened, as she falls asleep during the incident. To protect her, Kang-wook goes to jail in place of Yool-ju.
Five years later, when Kang-wook is released from prison, he meets with Yool-ju again, but Yool-ju is engaged to Tae-hyeon. Learning what sacrifice he has made for her, Yool-ju wants to return to Kang-wook, but this time Kang-wook is not alone -- Ja-kyung, his former classmate and currently a radio program host, is beside him. The circumstances hamper Yool-ju from loving Kang-wook, but she is desperate to help him recover the lost five years and become a top-notch cook.
This is a story involving vampires. It goes back to 350 years + when Baek Jung Won saved the vampire I-Wha from being burned at the stake in his village. He fell off the cliff while they escaped and I-Wha had to give him her blood in order to save him from dying and thus Baek Jung Won was transformed into an vampire also.
In the modern day Seoul, they opened a bar. One day Baek Jung Won received a letter from his former love who was dying and entrusted him to look after her daughter Jang Ji Yun . Baek Jung Won fell in love with this woman some 20 yrs ago but broke up without telling her the truth about himself. After her mother's funeral, Jang Ji Yun found a picture that her mother treasured a lot with someone looking like Baek Jung Won in it and she set out to look for him. When she finally found him, she thought he was the son of her mother's long lost lover as Baek Jung Won's appearance didn't change as a vampire. They start to fall in love and I-Wha has difficulty dealing with that. At the same time a serial killer who sucks blood from the victims is on the loose...
begins as Domyoji holds an extravagant press conference to announce his wedding to Makino the following spring. The press is playing her up like a modern-day Cinderella and everything seems to be going well. Later, the families offer congratulations to the couple. Even Domyoji’s mother—who was formerly vehemently opposed to the relationship and tried desperately to break them up at every opportunity—is suddenly happy for them. She even offers Makino a family heirloom: a tiara worth 10 billion yen (about $95 million USD) called “Smile of Venus”.
Later in their hotel room, Makino begins to worry that her life is about to take a drastic change from what she’s used to. Domyoji consoles her by telling her he’ll spend the rest of his life protecting her, but just as he says that a man dressed in black crashes into their room through a window and steals the “Smile of Venus” tiara. Domyoji tries to chase the man but he vanishes into the city. By the time they get back to the hotel room the glass is completely cleaned up and the window is replaced as if nothing had ever happened. Obviously there’s some sort of conspiracy going on. Could Domyoji’s mother be meddling again, hoping to make it look like Makino carelessly lost the tiara herself? Or is someone at the hotel trying to cover up the crime? Domyoji and Makino are determined to get to the bottom of things, and end up going on a wild adventure together which takes them through Las Vegas, Hong Kong, and various places throughout the world. And don’t worry fangirls, the rest of F4 will show up too.
