First, Sir, pls guard your speech
Second the AIO from page 1 here provides only version R14, but recent AI version of BetterRepack is R15. Go there

and choose AI Shoujo on the left side
Third you should know the BetterRepack including game, lot of mods and base version of StudioNEO is actually only 51 GB to download. The "Optional Sideloader Modpack Studio" (146 GB) is ONLY for StudioNEO and makes only sense if you want intensively work with Studio.
Last but not least: to avoid the messy installation of splitted packs follow the recommendation of pepplez and download via torrent - I guess you already did so.
For R15 torrent file is directly here

, you can deactivate the optional studio pack before starting the download, if you want.
Good luck
