@Airwave2k2 don't know if it was a typo that's been fixed, but the page you're talking about says that she's an idol to the first years, guy even calls her Ayabe-senpai, she's not a 1st year.
So the dude is just a first year. Guess i was confused because owl-chan was childhood friends with rabbit-kun and the dude speaking to her was in my mind the same age.
