Before I go on I am a Homosexual man so I'm probably not the demographic aimed for this game, so I have no biases whatsoever.

Being real for one sec I don't hate the first Huniepop,
I don't like any of the dating sim parts but I felt like the puzzle part was actually fun.
Huniepop 2 ruined both the dating part and the puzzle part, it turned a fun at times "sexy?" puzzle porn into a repetitive slugfest that was neither fun nor sexy.
I hate games that are really bad
but I really hate stuff that wastes my time.

So much of this game feels like padding for time because they didn't have that much content for a whole sequel.

There are 12 girls in the game, and you have to have sex with 1 of those girls about 4 times with another girl. Overall you have to have sex with 2 girls about 24 times to get to the final boss, but you also have to date 2 girls at least 1 time in order to get the sex
that means in total the number of dates you need to go on is 48, not counting for all the times you will fail since the new mechanics they added making the game way too fucking hard.

Look man if you wanna jerk off to something just watch porn online for free, this ain't it chief.
