(The yingdu arc is like if you combined the dramatics of season 2 with the sillies of the chibi series with the shipping of the manhwa).
But the idea of Cheng Xiaoshi being aroace and just being flirty as ~his personality~ (read: part of his mask)
Along with Lu Guang being gay. Just ridiculously gay.
So they're in a 'really sappy, constantly teasing each other, qpr coded, label-less' relationship...
... and yeah it makes more sense in my head because literally their queerness is practically cannon. (Including Cheng XIaoshi being aroace... I have evidence -> when Cheng XIaoshi dived and lived as other people with crushes he describes their feelings as if they're foreign concepts to him because they areeee.)
Also I'm very tired so tired 3-5 hours of sleep for this week this night owl is not made for society sob
