Before He Zhilan had a chance to glance at the opened letter, Jiang Biyun quickly grabbed it from her. Calling over Chen Xiting, the two of them hid in a corner, casting sidelong glances at the letter while keeping an eye out for Zhilan attempting to snatch it back.
Interestingly, Zhilan wasn't fazed at all. She knew He Teng too well. Given his personality, it was unlikely that the letter was filled with sweet nothings that could excite a crowd. It would mostly report what he's been doing recently and how well everything is going, just like the letters he sends home.
After Jiang Biyun and Chen Xiting spent over three minutes reading the letter - a few hundred words - they didn't find anything that could be used to taunt Zhilan. They didn't even find the word 'wife'!
