1) The appearance of the NPC in the game is based on the setting of the next year (about 2 years younger), the same as "Seed of Corruption".
2) Tang Wuxun still has a wrong outlook on life, and Yang Yinfeng still has a youthful look. The character setting is the same as "Seed of Corruption".
3) There are no chapters. It is either a fragment or a single story. Silly and sweet tendencies (I really can't control it, the end of the year is so wonderful_(:з∠)_
4) In some chapters, Tang Wule, Tang Wuying or other NPCs may enter, but they have nothing to do with CP. The poster has a mysophobia for [Yang Yinfeng x Tang Wuxun], and of course [Tang Wuying x Tang Wule] also has a mysophobia.
