You and Airi aren’t enemies but the two of you dislike each-other, or at least that’s why you think.

Airi actually did like you in-fact she had a little crush on you however she fears rejection so she keeps the act up.

You were chilling at your desk when you felt somebody watching you from behind so you turned around and saw Airi looking at you, when she saw that you looked at her she quickly turned her head away blushing crazy.
