For this ask game; so I’m mainly going by The Untamed, b/c it’s been a while since I read the novel and I’ve only read it once:
How I feel about this character: I love him and also he hurts my heart! I watch the early days and I wish to the depths of my heart that he lived in a softer world that allowed him to focus on the things he really cares about — the birds and the painting and chilling with friends. Not what he got instead — the war and the murder of his brother and 10 years of terror while he hid in plain sight making nice with his brother’s murderer and growing harder and colder inside year after year. It hurts! I don’t like it! And also, I’m angry with him for the way he used people during that time of plotting — I don’t know what happened with Mo Xuanyu (we can’t know, of course), but that was a vulnerable young man who committed suicide when he didn’t have to, when he might not have if he had been given a better life. And I do know what happened with Lan Xichen and I’m miserable about it! Hahaha, turns out there’s a LOT of feelings in me.
All the people I ship romantically with this character: I’m an inveterate multishipper, so the answer is — I can be convinced to ship just about anybody with him (just no one from the older generation, thank you very much). I’m partial to SangCheng, of course. But I also think SangNing would be really nice and we should think about that more often. :3
My non-romantic OTP for this character: Wei Wuxian & Nie Huaisang BFFs! I want way more of that pretty much always. Also the Cloud Recesses Trio (WWX, NHS, and JWY) as a platonic OT3 is excellent.
My unpopular opinion about this character: I’ve made an entire post about this, but it seems to be a popular opinion that Nie Huaisang has spent the time after his brother’s death entirely alone and that he ends up alone post-canon. I disagree. He has an entire sect of devoted disciples, who must have been the ones to help him set his machinations in motion! I think he has a lot of people he cares about back home in Bujing Shi and who care about him. They’re just mostly off-screen, b/c he was keeping them away from the machinations for their safety. But Fatal Journey gives us a glimpse into Nie sect dynamics and I think of it as canon, pretty much.
One thing I wish would happen / had happened with this character in canon: Two things. 1) OBVIOUSLY DA GE NOT DYING WOULD BE GREAT! 2) During the time when WWX is in the Burial Mounds, I wish Nie Huaisang had been able to go to see him. WWX was his friend! In the drama, NHS specifically shouts to WWX to take care when they’re heading off to Qishan! I want them to spend more time together and for that to maybe change things.
