This was one of the plots of King Deer's Daoist writings. In the Taoist writings of King Xun Lu, Wu Shixun and Lu Han used to be a couple, but they later separated for various reasons. In this scenario, Wu Shixun began to write in his diary every day. He always wrote that today, Lu Ge sent me a text message to express his thoughts and concern for Lu Han. This plot was usually used to describe the psychological changes and emotional ups and downs of Oh Sehoon, as well as to show the brotherhood between them. King Deer's Daoist writings usually involved the complicated relationship and interaction between them, as well as the misunderstandings and reconciliation between them.
