Only those who truly care about you will mind every word you say, and for those who don't care about you, no amount of talking will be of any use, even if you shout yourself hoarse.
Just like the girl with the sparkling starry eyes named Tang Tang, in her eyes, Chu Mo might just be a senior she is somewhat fond of, a man who is mature and successful, unlike the average male. For her, the gap between her and Chu Mo was just too vast. Therefore, when she was with Chu Mo, she had a probing attitude.
If she could develop a relationship with Chu Mo, that would be great, but even without any development, she would not lose anything.
Thus, deep down, Tang Tang actually didn't care much about Chu Mo. Naturally, under these circumstances, she was rather indifferent to Chu Mo's propositions.
In such a situation, it was only logical for Chu Mo to be rejected.
Of course, at this point, saying something like "I never take back what I give away" would be rather redundant.
