Su Nanzhi probably received Jiang Beiyu's call around eight o'clock in the evening, just after she had shown An Yunhuai around the house and allowed him to spend some time in his room.
In An Yunhuai's room, Su Nanzhi placed two photographs, one of their parents together and the other the only family portrait of the four of them.
The siblings in the photograph were probably just a month old.
An Yunhuai indeed needed time to sort through his thoughts.
From an abandoned child to a beloved one searched for by relatives for eighteen years, what his feelings were exactly was not something Su Nanzhi needed or could concern herself with too much.
If An Yunhuai were eight, she would definitely ask, but An Yunhuai was eighteen this year, the same age as her, and there was nothing much to say anymore.
Adults should know how to adjust their mentality.
When Jiang Beiyu's call came, Su Nanzhi immediately answered.
"Su Nanzhi, you're not coming back tonight, huh?"
