Pure New Year's greetings.
It is written for readers who read HP's Smile (another article of mine).
If you haven't seen Smile, you might not understand it.
It's not a long story, and it's already finished.
The smile floated to HP after Biochemical 2 was killed by the demon Zheng Zhapia, and then I tried to remember the story of trying to go back.
That's all.
Therefore, there is no CP in this article.
