Izzy is easily the best girl (for me at least) but she gets dropped very early in the story whether the player wants her or not which is a huge disappointment..I didn't finish the game after that because judging from the changelogs she becomes even less than a secondary character afterwards while lolis stick around; oh well nevermind maybe I'm just unlucky with my taste in characters this time...
Edit: I was already having a bad day when I wrote that plus I remember having bad memories about this title back in the day because it replaced DMD..etc that I didn't even try it once till now..Anyways I went back and played it a bit more, the main girl 'Melody' is not bad at all it's just that having the first sexual encounter in game with a stunning chick like Isabella makes you keep hoping for more and that's where I was coming from with my comment above, the closure the author gave her mini route is a nice touch but having her as a major character in the story would've been much nicer if not perfect for someone who took a liking to her like me..Anyways good game but it has it's flaws like I mentioned.
Edit2: BTW the protagonist is a pussy and has some weird tastes, what man loves having sex with condoms? Because he keeps bringing it up all the time, if he's afraid to come inside then he should just avoid a creampie? Or even better ask the girl to use birth control pills or something..Far better than doing the unsexy condom sex, not to forget the way he let his ex treat him not once but twice in front of Melody, that was extremely pathetic and made me completely detach myself from the protagonist, he gives off major submissive beta vibes.
