There Is No System, and I Am Not a Weakling.

A student who traveled through time and became a Pheasant University. He has been an ordinary person for two lifetimes. He doesn't even have a system. How can he get along? I originally planned to develop steadily and live my life easily, but unexpectedly, my school beauty became successful. He didn't want to lose his girlfriend, so he could only be forced to speed up the pace. I can only work hard to learn music knowledge, practice singing skills, and pick out the songs in my mind bit by bit, so as to remain invincible in the cold society.
