Which episode is Yan Yanyan being pinched?

It should be between 15 and 18, because in the cases of 17 and 18, Qiu Yan was graded in the teaching workshop department, and Liang Yi came back to see her. They pretended to quarrel, but in fact they exchanged information. Liang Yi accidentally dropped her key. When Qiu Yan saw it, she opened her own key.

Whose director Qin Xuan and others rushed up to save Qiu Yan and found their hands locked. They had to cut off their contact because of the loss of the key. Back to the chopping place, Liang Yi used a special tool to cut the links in the middle of the bracelet. As for the enemy bracelet, it was originally a tribute of Tofu Luo, containing high-precision organs and units, and the key could not be copied. If it is forcibly opened, it will definitely hurt the skin. I just sent someone to Tofu Luo to find a craftsman to rebuild it. It takes more than two months to go back and forth.

That looks like a bracelet, and there is a person who is particularly like a token of love. Whose director Qin Xuan is jealous, Qiu Yan also feel inconvenient. At that time, Liang Yi was engaged to her sister Qiu Min, which was controversial. When Qiu Yan returned to the office, she was very worried and afraid to see it, so she wrapped the bracelet in a towel. Qiu Yan stared at the wooden bracelet, thinking of many things before, suddenly feeling a little flustered, and quickly wrapped the bracelet in cloth.
