Shi Nancang still had Shi Xiaoya's house card.
Luckily, after Shi Nancang learned that Shi Xiaoya and Han Zhuoling were living together, he did not dare to come as and when he liked as he had done in the past.
But he still felt that his younger sister had been taken advantage of and was unhappy with Han Zhuoling.
This kind of feeling he had was similar to Shi Guanzhong's.
Even if Shi Xiaoya and Han Zhuoling had already grown old together as a couple in the future, Shi Nancang and Shi Guanzhong's attitude would not change.
But attitude was attitude—they still had to respect their boundaries.
Leaving the house card with Shi Nancang was just in case anything happened, in case any unexpected situation came up.
But he would not be able to come as and when he liked as he did in the past.
What if he bumped into an awkward situation?
