Yujia had seal stamps before. She got one to complete her generic mountain paintings in the past. After becoming a Lingxin disciple, it was only natural that she got a few more, but they were all studio stamps to mark as the work of Lingxin. She didn't mind those, and actually used it. They were made of a plain white jade, essentially the same material as the Lingxin pendant she wore on her waist.
As for why she had never bought herself a personal seal: she never actually gave her seals much thought or appreciation, considering that she wasn't a famous artist. Adding a seal on her artwork wouldn't make it sell faster. However, now, considering that she was much more interested in pursuing the arts for reasons outside of finance, she was actually quite delighted to receive this present.
second male lead syndrome, anyone? ;u;
(but is yushang really the second male lead ay ay?)
(maybe he actually is)
(or maybe there's no such thing as 2nd ML in this story)
(maybe yushang's secretly a girl)
(maybe he's the 2nd female lead)
(or maybe this genre is secretly BL)
(and he is yujia's love rival. yushangxzixu all the way)
(who knows?)
(haha dont mind me my mind isn't normal right now lolol)
