Okay, can we just talk about how GOOD Nangong Rang and Ruan Xingci are together? Like, I know this is supposed to be a political marriage but the way they operate as a team is genuinely satisfying. She's out there slapping nannies and flipping the script on every scheme the family throws at her, and he's right there coughing awkwardly like 'honey, maybe don't burn the whole house down' but also... he doesn't actually stop her. He supports her. When Second Madam tries to trap them with those two 'gift' maids, Nangong Rang is the one who steps in and says 'we have enough people in our courtyard' — he's protecting her from the setup. And then later, when they're walking back and he says 'You've made many enemies today,' it's not scolding. It's almost... impressed? Concerned, sure, but there's something else there too.
The moment that really got me was when Ruan Xingci reveals she's a transmigrator. She's sitting there being all self-deprecating about how nobody in Beiguo valued her either, and Nangong Rang just... opens up. He tells her he knows why her mother-in-law is the way she is, and more importantly, he admits that SHE helped him out of his own miserable situation. 'It's a good thing you were willing to help me out of that situation, otherwise my plight might be even worse than yours.' That's not just gratitude. That's two broken people recognizing each other. They're both outsiders in this family — he because of his health, she because she's from another world entirely — and somehow that makes them the only two people who truly understand each other in that entire household.
