[Mushishi] This Kyougoku Isn't So Cold

An AU of "Leon: The Professional" Meng, the gangster boss's youngest son x Ke, an illegal immigrant assassin in Britain I watched the movie quite a while ago, so I've only borrowed a little of its setup. Think of it as a gangster story: Meng, the youngest son of an American or Russian mob boss, x Ke, an assassin who smuggled himself into Britain. * There is a significant age gap. The ending mentions that A Meng disguises himself by dressing as a woman. Neither of them is a good person. There are significant alterations and original details. Apologies if the characters feel out of character. If you're okay with all that, enjoy the story! Theme: Life has to go on
