Han Fei
His works ultimately ended up in the hands of the thrilled Qin king, Ying Zheng, who commented, ""If I can make friends with this person [Han Fei], I may die without regrets"." and invited Han Fei to the Qin court. Han Fei presented the essay "Preserving the Han" to ask the king not to attack his homeland, but his ex-friend and rival Li Si—who was jealous of Han Fei—used that essay to have Han Fei imprisoned on account of his likely loyalty to Han. Han Fei responded by writing another essay named "In the first time of meeting Qin king", hoping to use his writing talent to win the king's heart. Han Fei did win the king's heart, but not before Li Si forced him to commit suicide by drinking poison. The Qin king later felt regret about the unfortunate death of Han Fei.
