2 years, huh...
Honestly, the ones that do it in like a week feel a little off to me (unless it's Hentai where doing it on day 1 is more than possible), but 2 years might be a bit too long...
Even more so because it's Hentai.
That ending was quite cute, though, I kinda liked it.
I love the irony in this one, in the beginning the chick was extremely aggressive, when at the end she almost seems traumatized.after she realizes that she has bitten off far more than she could chew. Oh the Irony is so Sweet. :3
...Wait, you meant PERSONALITY. Um... yeah... that was totally my first thought as well. I swear.
