"What 'me?'" the man huffed. "Let's go have breakfast."
This attitude... He's obviously still in a huff. But by now, Xia Wanwan probably had an idea of what he was upset about. Although she had been drunk, she was quite sure that nothing had happened last night, so this man must have been infuriated by her then.
Out of guilt and shyness, Xia Wanwan was exceptionally compliant today, her fair little face constantly flushed with red.
Xi Muchen didn't say much, but his attitude was off the entire day, making Xia Wanwan feel that, although he was clearly angry, she couldn't quite pinpoint what he was angry about with her. He seemed normal and didn't show any behavior that indicated he was angry with her or say anything angry, but... it just seemed like he suddenly became a bit tsundere, enough for her to see that the man was indeed annoyed.
