Among Sheep - OP Returnee LitRPG

[The SYSTEM has arrived.]

Kai wakes up in an unfamiliar environment, with the words projected into his eyes. At some point, he faces a question he's never encountered before:

"Are trashy novels really the only heart demons I have left?"

Things to expect:

OP. MC wins. OP means overpowered.Mild character development.Side characters do things that make sense.

Fiction is less sassy than this intro.
