Sharingan? But I'm in Crayon Shin-chan!

[System + Transmigration + Fanfiction] [Friendly Reminder: This story is not purely slice-of-life; there are battles and characters.] [The protagonist's name has been changed; please point out any inappropriateness.] Gu Feng is a good young man from the 21st century. After a friendly one-on-one conversation with his boss who owed him three months' wages, he transmigrated to the world of Crayon Shin-chan, awakened an emotion system, and began a not-so-leisurely life.

[This is a new author, I hope everyone can give me lots of support. Please point out any shortcomings.] [The plot is not original, and the theme is very old-fashioned.]
