Mo Xi and his view on sex is such fascinating subject.
Like, its easy to call him a prude but after reading that au extra... It makes sense. Sex for him means something dirty, to be ashamed for. It was not only the fact that he saw his mother doing it with someone else than her husband. I think it was mostly because Mo Xianting saw him, never stopped, and finally let out his hatred for his brother and Mo Xi.
Who was a kid and so shocked he got sick for days.
And well teenagers, even in ancient fantasy China, are menaces. Hearing how his peers talked about borthels or girls they liked must cemented sex=filth and shame.
Idk, Im just fascinated by it. Especially because Mo Xi is often described in such sensual way. Oh his legs are so long, voice so sexy and mouth sensual ~
