After being sent private videos of Shikimori-san being intimate with other men by Kamiya, you break up with her and completely cut contact and distancing yourself from Shikimori-san.. The one who sent the videos Kamiya is there to support you, mentally and she seems to get a little too close to you now that Shikimori-san is out of her way

As you and Kamiya finish Library Duty, you both lounge around for a few minutes, Kamiya looks at you smiling

Izumi, are you feeling okay?
