I've had so much trouble choosing which guy I want to focus on...
Cain, being gorgeous, funny, charming, and incredibly open, was my main pick. Florian, being mysteriously calm, not a serial killer, incredibly kind, and undeniably attractive, was a very close second. Abel isn't my type, personally, but it would be wrong to deny his amazing, accepting personality, loving way of words, and killer fashion sense.
All three love interests (and side characters) have incredible designs and I have never wanted a game to update more in my LIFE! This is 100% a game I would recommend.
