This game has a really misleading title. You would think this is a continuation of the previous game, but actually the developers pulled a fast one on you. There is very little NTR content in comparison to the entire game overall. The game cuts into Mr. Wang from the first game banging the first heroine in a scene that's presumably after the events of the first game's first chapter, but then the game pulls a fake-out introduction. Turns out the events of the first game happen in a video game that the MC of this game was playing at the time. This game is actually an improvement when it comes to plot and characters, and it isn't too annoying with clicking through h-scenes like the first one was.
That said, the most glaring things for me were the voice-overs and the save function. The voice-overs range from decent to awful. Decent is about what you expect, and awful is when it becomes an issue. You have to adjust your voice-over volume manually, because in some scenes... the VA may be speaking too loud or speaking so low the music drowns them out. Some of the VAs have ongoing issues with sound quality. A few of them sound like they're talking behind a wall and another one echoes like she's recording in her bathroom. The save function is a bit annoying. So, you
can save. The problem is that the saves will bring you back to the start of the scene - they don't save at the exact same part. This is pretty workable, but the problem starts happening when you get to long scenes.
Also, if you're still confused as to why this game is titled the way it is.
