Classroom of the Elite? Nah

In the worlds of full of lies, deceit, danger, and adventure would I remain the same with the second chance that I have been given? A strong willed prodigy, now unshackled looking for the meaning of the second life that he's been graced. Is it a curse or a blessing? OP MC, with a working brain. Harem? Up for consideration. Still a novice writer here, please be lenient :)
