@TheDarkn3ss has written an excellent instruction on where you can find the mods folder.
If you need more instructions on how to install the mod:
1. Be in the 'mods' folder.
2. (If you have not already) Download this mod or any other mod and open the file with WinRAR or other extraction softwares.
3. Place (in this case) 'Standard Harem Main Protagonist' folder into the mod folder.
4. Start the launcher of 'Strive For Power'
5. Click on the mods button, select 'Standard Harem Main Protagonist' and apply the mod.
6. Your game will shut down to replace the data, so you have to restart 'Strive For Power'
And there you go, it should work now!
