It contains some small extras from the two books "Sweetness and Bitterness" and "But He is a Lonely Little Beauty". There will be some stories about Xu Junnan before he met Jin Yuchen, and there will also be some stories that happened when Yu Ze was still alive.
The overall tone is the tragic tone of "Sweetness and Bitterness", which can be a bit sad~
Mission: Peace, love and common progress
