Gu Yanyu knew nothing about her older brother's love life until one day he told her that her little nephew had been born. She was stunned.
Watching her brother grin foolishly at his newborn son, she couldn't figure out when he'd started dating Sister Jingshan, let alone gotten married and had a child. So...
Gu Yanyu: "Tsk, I've always wondered how you managed to keep your relationship with Sister Jingshan a secret from us!"
Gu Jingxing glanced at her, then continued playing with his newborn son. "We never really dated, not in the conventional sense."
Gu Yanyu: "What a jerk!"
Gu Jingxing smiled. "I've known since we were kids that I'd marry her. Whether we dated or not made no difference."
New author, new story. If it's not your thing, don't read it.
(I don't think these two have a normal relationship.)
Theme: The quiet joys of an ordinary life
I want to read the follow-up. Does the author have any more updates?
