Ye Mo might not admit it, but he really liked Liu Ran's temperament.
After fetching him, they went on to visit Liu Liushi to inform her of the news and ask her to look after the house.
So, on the way to their destination, Ye Liu told Liu Ran, "Ran Er, your sister and the four of us will be going to the capital for a few months. This is your first year in school so we can't take you. But we'll definitely do that next time! As for the house, we'll ask your mother to come stay for a while, so you won't be alone after you return from school."
Liu Ran listened silently. He regretted that he could not go but, between fun and academics, he decided his studies were more important!
When he heard his mother was coming to stay, he was obviously very excited.
