The story revolves around four young people. After the death of the president of Sung Han Group, a very prominent group in the world, the heir was to be decided. In the midst of all the commotion, his biological granddaughter was discovered, Jung Hween-Lin, and brought to live in the main house. Though kind and softhearted at first, the money changed her and she became very spoiled and obsessed with her bodyguard, Han Jae-Ha. Han Jae-Ha was initially raised by the president to become the successor of Sung Han Group, but instead now he's become nothing more than a Jung Hween-Lin personal bodyguard and head of the security in Sung Han Group. In order to fully protect her he hires a policeman, Baek Suk-Ho, who despite his old age looks very young and fits in immediately in the high school that they are attending. He joined the police force so he could legally beat up people and doesn't care much about rules or the consequences his actions produce. On one of his missions he meets up with Yoon Lee Sem, a biker gang's leader, who with just a few sentences convinces him to destroy his police cars and makes a breakthrough. Almost causing him to lose his job because of that, he reluctantly accepts the mission to guard Jung Hween-Lin. He then meets up with Yoon Lee Sem once again at high school, who looks completely different from the last time he saw her, which makes him not recognize her at first and befriend her. She, too, becomes Jung Hween-Lin's bodyguard, for unknown reasons, and it seems that Han Jea-Ha and her known each other from before, which adds more to Baek Suk-Ho's suspicion about this whole mission.

Three strangers ally with each other to survive a Battle Royale style game of death on a deserted island against other contenders. A lot of contestants have amnesia and each person has a life sustaining bracelet which heals wounds over time.

Nearly 2000 years ago, the prosperous Han dynasty of China collapsed. Heroes rose and fell, and three nations emerged--Wei, Shu, and Wu. Historians refer to this period as the Three Kingdoms period. The romance of the three kingdoms is an intriguing tale of heroic deeds, of alliance forged and broken, of loyalty and betrayal.
Hong Kong artist Chan Mou retells this classic tale in "The Ravages of Time" from the perspective of the Sima clan, which in the end united the three kingdoms. Readers will be attracted by an array of well-developed characters and Chan Mou's own unique top-notch art-style.

From MangaHelpers: In a hidden school surrounded by mountains, young ladies of good families are taught everything a high class lady needs to know. They are also completely cut off from the outside world, keeping them sheltered and innocent. However, a problem has come up recently-- more and more graduates are failing to cope with the modern world after graduation. To deal with this problem, they've decided to kidnap a male commoner student, and enroll him as a student. They hope that this will be a gentle way to introduce the girls to the outside world. Kagurazaka Kimito is chosen for this dubious honor, mostly because he seems utterly average. However, the school leaders also seem to have concluded he's a homosexual with a muscle fetish. When Kimito hears that the alternative may be castration (to protect the girls' purity), he eagerly plays along with this misconception. Now he'll just have to survive the attention of many high class young ladies that are completely out of touch with the world! [tethysdust]
