The gong starts thinking he must have a split personality that comes out when he's unaware, and this other personality of his is a piece of tr*sh who seduced the vulnerable shou and treated him like dirt. What if this alternate personality of his is a criminal or serial killer?! And so now the responsible gong must figure out what's going on, what triggers his personality switch, and deal with himself! And reassure and take care of his poor dear spouse at the same time! *facepalm*

So his master was brewing "yang potions" for all of the vampires in the country or something, which potions make them resistant to sunlight (maybe?) and give them super strength or something, but I was honestly confused as to why he was doing this since vampires are supposedly so evil. The story does sort of explain in bits and pieces but it doesn't make sense—at one point I thought he was trying to reform the vampires, but later it sounds like the vampires forced him to do it against his will, and he walked right into their trap because... angel-pigeons are unreliable and despite saying they'd help the master, they never showed up. Also, there's apparently some kind of global Magic Council that oversees all magic and supernatural creatures including vampires who must abide by the council's ruling, but this vague council just sort of exists as a background explanation for why things are without actually explaining why things are, and despite being so powerful seems powerless to stop, affect, or change anything that's happening.

This is all revealed in bits and pieces breezily scattered here and there throughout the story so it makes it especially confusing trying to put together what happened and why. Perhaps if I had read the story in one sitting instead of chapter by chapter as it updated it would have been less confusing, but I'm not sure on that and it's pretty telling that now that the main story is complete, I have no interest in going back to reread everything to see if it makes more sense read all at once.

There's a confusing plot point involving adding rare super magical diabolos blood to the potion, because it makes the potion more powerful, but while the story made it sound like that was the master's secret potion ingredient, apparently Xia Ke is the first to use it in the yang potion, and it has some kind of poorly-explained secret negative effect on the vampires that leads up to the very underwhelming and barely-described ending involving an undescribed fight between pigeon-angels who show up suddenly on time against a legion of the most powerful vampires in the world (if you're confused, so was I) and then the vampires suddenly exploding into puddles of blood due to drinking the yang potion and yeah, idk, it was all pretty lame.

The only concrete thing I know is that Xia Ke's master blew himself up in a kamikaze move against a bunch of vampires. Because of some reason. I'm unclear as to why he couldn't escape or bluff or bribe his way out—especially the latter two, considering how utterly s*upid and incompetent the vampires are. It's hard to tell if they're s*upid because this is supposed to be a comedy or if they're s*upid because the plot wouldn't work otherwise.

The ML thought he had developed a split personality because he couldn't remember marrying the MC. After getting blackout drunk once, he saw the MC was hurt and assumed he himself was a gaslighting domestic ab*ser. He became convinced that every time he drank, his other self emerged (he thinks he has a double personality). It made me wonder whether he always drank until he blacked out.
