Upon returning to the Qiao Family's mansion, Luo Qianxun took the children upstairs, and Li Mingxun tried to follow but was stopped. "The upstairs is for the hosts, you can't come up," she said.
With a single sentence, she had clarified their roles as host and guest.
Since they hadn't remarried yet, he wasn't considered Qiao Family's son-in-law and therefore was a guest.
"Honey, but we..."
Li Mingxun tried to point out that they had two children together, and his status was pretty clear.
"What if we have children?"
Luo Qianxun scoffed, "There are plenty of people who have children out of wedlock."
She took the children into the room, not giving Li Mingxun a second glance.
Li Mingxun awkwardly stood in the living room, unsure of whether he should go upstairs or stay downstairs.
The real dilemma was that no one came to show him where to go, so he didn't know where he should be.
