Review Detail of bop_2803 in Dual System: Ascension of A Nameless Nobody

I am still in volume one (chapter 35) and I don't like the main character's actions. I understand his reason for saving people. I just hope he doesn't save and involve himself in everyone's problems. Other than that, he's pretty relaxed, relatable, and nice. I also love the first two side characters and the fighting scenes. Very descriptive and easy to imagine. One question will there be one female lead or harem?
