Bai Siyao knew Chi Xingye's character well; when she said that, it was because she didn't want to owe anyone anything.
She was always rational.
Friendship, romantic love, familial love - she always distinuished among them clearly and never overstepped boundaries.
Even though his heart was a bit disheartened because she was so particular with him, it didn't matter because he had plenty of time. He was always patient with her.
One day, she would realize his sincere intentions...
At that moment, he smiled and responded, "Okay."
...
Mo Bing, carrying a thermal flask, hurriedly rushed to the hospital at 6 am to relieve Chi Xingye in taking care of Bai Siyao.
"Xingye, you should go back and rest, I'm fine now."
Bai Siyao understood her principles - even if he wasn't severely injured, she wouldn't abandon him at the hospital. That's why he informed Mo Bing to come over.
"Yes, Xingye, I'm here to look after my brother, you don't need to worry." Mo Bing chimed in as well.
