Lin tells jokes to Qian Sanyi.

In the TV series Pi 2, Qian Sanyi, a fictional character, and Lin, an angel, had a quarrel because they misunderstood that their relationship was not as good as before.

Once, Qian Sanyi in the novel ran downstairs in the company where Lin worked and accidentally met Lin's boyfriend Lu Jiawei. At this point, Lu Jiawei is talking to a girl on the phone, and her tone is too intimate. Qian Sanyi couldn't shout well, but Qian Sanyi still kept silent. After returning home, Qian Sanyi investigated Lu Jiawei's related information and materials. He saw Lu Jiawei's social account and found it clean.

Lv Jiawei is engaged in the media industry, but his social account is very unusual. In addition, Qian Sanyi met a video of a peacekeeping girl downstairs in Lin Company, and her tone was too affectionate, which made Qian Sanyi alert and worried that Lin would be cheated. Qian Sanyi immediately told Jiang Tianhao about the abnormality he found, but Jiang Tianhao didn't think so. In the last secret room, Lu Jiawei performed very well in the game. Jiang Tianhao's attempts were fruitless, and Lv Jiawei was also very kind to Lin. He wanted to pick Lin up and take her home, so Jiang Tianhao didn't care too much, but Qian Sanyi didn't feel very relieved.

So, while helping Jiang Tianhao carry the roadside dining car, Jiang Tianhao opened the dining car downstairs in Lin Company, and Qian Sanyi also came to help. Jiang Tianhao also called Lin for help. After some thinking, Qian Sanyi was worried that Lin really met, so he met Lv Jiawei in a girl's video while running downstairs in Lin Company, and told Lin about his experience in an overly affectionate tone. However, after seeing Qian Sanyi that morning, Lin misunderstood Qian Sanyi, and they had a quarrel and broke up in discord.
