Kiyonori tries to reason with her but she states that he has no right to lecture her for he’s never been in love. Only when you try to stop her from entering the hotel room, did she see that you were right. After Kiyonori saves her and you, he's seen going into a love hotel and takes the blame to protect the two of you and resigns.

He'd had snapped a picture of the two you and sent it to Ms. Kiyokawa which brought your relationship to light.

Since then, there's been bad blood between them and he'll do anything to hurt Rikiya, even allowing his friends to gang-rape you when he thought you were Rikiya's girlfriend. He even used Rikiya's student Sanada on several occasions to lure him out. He then showed up at the school and tried to stab Rikiya, but you protected him.
