Once it started, it was out of control. The Locomotive Tower finally lost his life because of the intoxication when he was young, and because of a travel plan when he was young, the little Sanxian was trapped in the fireworks belonging to the Locomotive Tower. So Youxian had his fireworks locomotive to accompany him throughout his life. They also reflected the immortal secret that cannot be leaked. What is clear is unclear. They have never clearly expressed their feelings, but everything is clear in their hearts.
Concept: What you think is not necessarily the truth, it is how the protagonists feel about each other, but what you think does not mean everything. Even if you don't understand, you will still understand everything from the other person's words.
