"Jia Jia, I burned the midnight oil last night. I put in all my effort and finally solved it!" Wang Zhitao said as he held the question paper with answers.
"Really? You solved it by yourself?" Zhou Jiajia asked with a smile.
"Yeah, this question was really not easy! I guess only a few people could solve it!" Wang Zhitao said it in a big way.
"Oh, I thought you asked someone else." Zhou Jiajia grinned.
"Ah?" Wang Zhitao was stunned and immediately said, embarrassed, "How could I ask others? I solved it myself."
"Really. I thought that the person who asked me this question last night was you." Zhou Jiajia shook his head and said plainly.
"What? Aren't you Charming Baby?" Wang Zhitao was stunned. " 'I'm a Little Hacker' is also you..."
"That is my sockpuppet." Zhou Jiajia nodded.
