It seemed like Li Chuntao's assumptions were correct as Mu Jianyu found himself being preoccupied as he waited for Ying to respond to his messages. He didn't want to make her uncomfortable by asking her questions but he couldn't help but be worried about her.
Shen Zichen had just moved next door to them and his presence wouldn't be good for their relationship. Even if Ying had rejected Shen Zichen's feelings for her, it didn't mean she wouldn't be able to grow fond of him.
How was he supposed to stop it from happening without making it look like he was causing discord between the two? Ying might take Shen Zichen's side if he started to make an issue out of it.
It's been an hour since he reminded her about lunch but Ying hadn't responded to his message. Was she busy? Did she go out again to visit the orphanage, or meet other friends?
