I also put myself in his place and people try to avoid him because they think he's too much, but being a bit unruly and not being able to grow up in the same conditions as others don't make him unworthy of affection, care, and respect. The more I see Butterfly the more it reminds me of a "trophy wife" and I feel so bad about it.
He doesn't get anything more, he's not free, he's never been so, he never had a family who could teach him other things to rely on himself or being useful in other ways, nobody is listening to him, his only "allies" are those two servants who just try to control his temper and that's it, he's away from his 'dad' and Yan An is just using his beauty to earn money and connections but that's it.
I get that he's maybe not the most attractive (intellectually talking), but he didn't have opportunities like Fei Yue, Bai Yu, or even Qian Han to shine in those fields, however, he's well versed in arts and many other practical and social stuff (he's the strongest in that field and knows perfectly how to provoke and play), it's not his fault that he's a bit dramatic and I really need Yan An to pay attention to him. :'c
I'm pretty sure if Yan An at some point needs immediate protection, Xiao Qiao (is that his name? Can't remember, lol) will be the one who'll jump immediately to protect her and will make it clear to everyone that nobody can step over Yan An, and honestly nor Fei Yue, Bai Yu, or Qian Han would do or could do something like that.
I'm so excited to see Butterfly's spring, he deserves it so much!!!! Also, he's no small thing, our boy is honestly Yan An's biggest weapon when it comes to harem fightings, social displays, there's no one more cunning, beautiful, and talented than him in arts, he also knows how to attract the masses, how to make others to admire him and give everything to him, he'll be the perfect spy in the high-noble spots because he doesn't have to be perfect like Fei Yue, he has an impressive net of communications, and he's also the only one who could love Yan An without caring about anything else, so yeah! I'm so happy with the author, I'm just waiting for his redemption!!!! I also love him a lot, he's the most hilarious, the cutest and most mischievous one (if the author gives us a night between Yan An and him I'll die of happiness). :")
