The game is only at the start, but this has definitely made the list of the top5 AVNs I am more hyped for.
It's quite refreshing seeing adult characters in the HS engine. The dialogues and the relationships between the characters feel natural and flow pretty well.
Sayaki is the character who intrigues me the most, but I also am really curious to see how the current relationship of the MC will evolve.
Also good job with the music!
