It was heavenly doctor Ling's singular tear drop that fell down his face and landed dramatically on the floor, that alerted Song Zihao of heavenly doctor Ling's feelings. It was almost cruel for him to say something like that to heavenly doctor Ling.
Heavenly doctor Ling had put in so much thought about whether Song Zihao was going to be able to travel, and whether he would accept it, or how to make him accept it.
Every step of the thought process has Song Zihao in mind.
Now for Song Zihao to say he wanted to quit, even before heavenly doctor Ling asked for something from him, it was cruel. It was harsh to say the least.
Song Zihao had not thought that heavenly doctor Ling would react like that, and instantly reacted to console heavenly doctor Ling, even if it didn't go along with his words of wanting to quit.
