I'm giving up on this only around ch. 22, and it's really frustrating.
Decent (accidental?) commentary on Chinese society, good slice-of-life writing with stuff going on in the background, a decent bit of actual thought...
But like, the MC is such a creep. Not in the usual overt ways, but in how he's constantly plotting ways to keep the girl in his apartment, and/or make sure she never leaves him.
I understand his desire to not have her walk away and leave him as a forgettable extra in her cool time-travel story, but that doesn't make it okay.
And the fact that the author successfully makes it realistic and convincing honestly makes it more painful to read than the standard waifu wish-fulfillment garbage we get (we see her try to have autonomy, have it gently crushed, have him employ the sort of subtle manipulation that abusive spouses and family employ). She's not some cool toy for him to play with—except apparently the author seems to feel that actually still should be. And that's bloody creepy, much more profoundly than standard stupid braindead hentai objectification or whatever.
