She was certain that this was the reason.
Mu Xiaoxiao smiled sweetly and her eyes were tender as she gazed upon him. "I know you're angry. I'm sorry. I shouldn't have done that last night… But relax, we'll soon…"
Aiyoh! She really wanted to tell him about the surprise she had prepared for him!
Mu Xiaoxiao was a person who could not keep secrets. She had to restrain herself to keep mum about it and it was really difficult for her.
However, the thought of him seeing the surprise she had prepared for him on his birthday and how surprised and delighted he would be made her grit her teeth and bear it, forcefully swallowing the words that almost erupted from her mouth.
"What?" Yin Shaojie asked, seeing that she did not finish her words and had stopped herself mid-sentence.
Mu Xiaoxiao was afraid that he had noticed, and thus diverted his attention to the matter at hand. "Don't be so upset, in a few days… I'll make it up to you, okay?"
