Every one of these is seriously great ^ω^ Especially Reborn: Mrs. Huo Is Beautiful and Badass Again [it's mainly about secret identities and taking down scumbags].
And The Rose Kisses the Moon [it's so heartbreaking, I still can't get over it].
Then there's After a Flash Marriage to My Scheming Third Uncle, I Fell for Him [it's super sweet too, need I say more?].
These stories have a little angst here and there, but they're still really sweet. If they were nothing but angst, I wouldn't have put them here.
