I just wanted to mention that i loved how the dev expanded Serena's character from the original Violated Heroine. She was always my most beloved character but having a game centered around her that is done by a dev who also had her as a her favorite (and it shows) has allowed her to truly shine as a multifaceted character that comes across as arrogant and sheltered but also very much sympathetic.
The whole prologue in particular is incredible in how it sets her up as a naive aristocrat who slowly learns more about sexual matters and unless you're a coomerbrain you will probably be enticed into protecting her purity or at least to rally behind our favorite blonde loli aristocrat in her quest to save her unicorn.
...am i reading too much into a h-game that doesn't have that much into a complex plotline? Maybe, but given that some of her comments during her pregnancy genuinely made me flinch from guilt ("people who do bad things are punished for it, but i still can't understand what i did to get punished like this") i have an impression these feelings weren't just an unplanned incident from the dev, so kudos!
