If you read the light novels then you will find out at a later point in the story it is revealed that Kushida and Horikita went to the same middle school and Horikita is aware of an dreadful act done by Kushida which when revealed will destroy her popularity. So Kushida takes desperate measures to expel Horikita and eventually Ayanokouji also gets involved in a matter where he risked his own expulsion. But even after that Horikita tries her best to get in good terms with Kushida while ignoring the probable dangers to Ayanokouji and class D. So Ayanokouji's trust in Horikita depreciated.
