The Goal Is to Become a Gold Spoon so I Need to Be Completely Invulnerable

This not my preference. I don’t like harem whether it was female MC or male MC. If you like it go ahead. Even if in the end MC choose only one to be her/his partner, I hate that author use side characters relationship just as flavour to the plot and not the characteristics of each character.
This story also the type of making drama appear out of nowhere, it’s not bad but if most drama comes out like that, if feels like the author are not creative enough to think other good approach. Why it can be bad? Because the plot holes will increase until it unbearable to read unless you shut down your brain cells and just read for binge read.
Well it was not bad enough to be called trash but it below average, the harem genre is the reason why I also hate the love triangle. Because these genre(harem &love triangle) share the same bullshit plot and flaws. There are some exceptions though, when the story can be good but this story are not it. Most story of these types produce drama/conspiracies/problems from jealousy and stupid mistakes(like literally stupid like adolescent mistakes).
This is just my subjective opinions. Up to you, if you want to read are not.
