Afterlife Department
50,000 years ago, Hell was destroyed because of too much Foul from the resentment of the souls that later turned to Soul Eaters and devoured everything in their wake, leaving nothing of Hell. The gods above in Heaven, in order to take care of the newly-died souls, created the Afterlife Department comprised of grim reapers. Huo Ling was delivering food that day when he met Yi Bing and the guy gave him a warning. When he arrived to the customer's unit, he was killed. Huo Ling: you set up a death flag for me! Yi Bing: I'm a grim reaper. I'm the flag myself. Let me help you solve the mystery of your death. Huo Ling: your sister! Alternative title: The Different Ways I Died at 23 Update: daily
Arrangement
Huo Ling, having raised well in the palace, is only a little shorter than Yi Bing. Yi Bing, although has some muscles, but not to the point they are exaggerated. Also, since no one has since Huo Ling for a long time, except to the people he interacted with the past years, they won't notice 'Huo Ling's change tonight, unless they are someone close to Huo Ling, or one with discerning eyes and knows Huo Ling.
The former's example is the royal family, and Hao Baiyun. Meanwhile, the latter's example is Gu Xingfeng. Unless any of them would expose 'Huo Ling's identity, which definitely they won't do, then 'Huo Ling' can do his task peacefully tonight and act like the original one, while having the original one in his arms act as his female companion.
