When KangKang was born, he congratulated his parents and drove them home. KangKang doesn't tell lies he changes facts. Death once had a near KangKang-experience. KangKang could never get a heart attack, his heart isn't foolish enough to ever dare attack him. Once KangKang didn't go school for 2 days, now it's called "weekend". When KangKang was written in Death Note, the writer had a heart attack.
