Does it have a novel? I'm getting impatient now. I want the divorce arc to come sooner.

Yes, There is a novel. If you look this up 錯愛十五年，宋小姐放手再不回頭 章節列表 You'll find it.
But Spoiler…..











It has a sad ending…. (There might be side stories but idk at the moment)

Thank you so much
Seeing the novel has over 400 chapters I guess the manhua will take time to complete.
