Synopsis 1: Lin Xing has two identities. One is a knight who represents justice, and the other is a demon king who represents darkness.
Both of them are him.
Synopsis 2: A newbie System takes a liking to the scumbag "Lin Xingyang," who acts one way to your face and another behind your back, and happily assumes it's found a good Host.
Never in a million years did it expect there to be such a thing as dissociative identity disorder.
Also known as:
#You've got to be kidding me. The kid I raised, my friends, my brothers, how could they want to sleep with me? This is all your fault#
#Why do you mess up every time and leave me to take the blame?#
#Can we please just play properly?#
#I'm not a scumbag#
Please note:
1. The protagonist has multiple personalities, and they will remain separate forever. They will not merge.
2. One personality is a natural-born scumbag who thinks he's on top of the world; the other is so gentle and charming it's deadly. The demon king is the minor personality, and the knight is the dominant one. One hasn't bent yet and may never bend, while the other is already bent. Everyone loves the protagonist, but not necessarily romantically. Family love, friendship, and brotherly affection can all show up at any time.
The minor personality is already a world-class scumbag.
3. Two male leads, more or less.
4. The story focuses on ambiguous relationships. Once a world is over, it's over. The same person won't appear in multiple worlds, though there may be irresponsible bonus chapters.
5. In other words, the protagonist won't truly end up with anyone.
6. Feel free to skip any world you don't like. The worlds aren't very independent.
7. Actually, the protagonists are all scumbags; they just have different styles.
8. The author isn't very knowledgeable about the theory, so please point out any mistakes politely.
9. The blurb is misleading.
10. Not recommended for readers who want to think too hard. It's rather... lighthearted.
