if you put this scene on a movie screen (is it called a happy end?) (гет)

"The first point in the charter for Systems of Happiness states that: 'For the purpose of narrative drama, forced metempsychosis will be applied mainly to orphans, terminal patients, and poor, disaffected college students.' Underneath the first point, some enterprising soul has scrawled: 'at a pinch, just grab a ridiculously average guy the audience can relate to'. 
Nowadays, almost all systems treat this line as gospel. System 9566 however… It vanishes manhole covers in front of rich housewives and promising scientists. It poisons happily married businessmen with two and a half kids and a house in the suburbs then transmigrates them into the Big Damn Hero they never wanted to be.
Unknown to almost everyone, Ning Xue is the happiest person in B city. Now how can System 9566 let that go?"
----------
Ning Xue is somewhat resigned to the fact that's she's been forcefully transmigrated. Thank the ancestors that it's a BL novel. In the world of danmei, women can only be cannon fodder(*) so she can just focus on cultivating immortality!
