[Crossover] In the Days of Attack

The male lead transmigrates, and the plot is a bit melodramatic. It's a story about a side character blending into a crowd of people. The protagonist likes to keep a low profile and play possum. He has the same interests and hobbies as an ordinary person. Also, his golden finger is the hobby he had in his previous life.

I expect this will get flamed a lot as I write it.

Also, this is a story about the male lead and his buddies goofing around together.
