(Quick Transmigration) What Do I Do After Entering an Omegaverse Novel?!

Quick transmigration is all the rage, and Systems rule the game. To compete for customers, the Systems come up with all sorts of tricks and offer every possible experience. Take the one I've got here, for example: the O-novel heroine rescue System. It actually lets customers customize their character at the start! Me: Great! I want fair skin, a gorgeous face, long legs, an icy, noble aura, and combat skills so strong they're off the charts! System: Um... you can only choose one. Me: I'll take the last one! And then? Then I got stronger. And bald. Even my whole look changed. Damn it, I should never have trusted the System to offer anything good!
