The first volume is a prequel to the protagonist's life and is dominated by emotional elements. If you don't like this genre, you can skip directly to the second volume without affecting your reading.
[Urban imagination, partial unit drama, no heroine, no system]
…
My desire is big, big.
Big enough to dare to carry out this audacious plan.
It is so big that it has collected seven emotions from scratch.
It's so big that it makes the "clam" a superior being.
Dragged into the mortal world.
Now that I have completed the seven emotions, I am the strongest desire, the combination of all emotions, and the last colorful stone to mend the sky.
Drawing a dream, maybe I should call you a "mirage".
——"Bang", the bubble bursts.
Enjoy your life.
