Suzune Horikita/Relationships

Manabu Horikita
Manabu is her older brother as well as the student council president. Suzune is shown to admire and wants to prove herself in his eyes but because of her status as student in Class D, she is seen as nothing more than an embarrassment to him. Despite her respect for him, she holds some resentment towards him as she got irritated when Ayanokōji asked if they were related but Suzune's glare prevented him from broaching the subject.

In Episode 2, she is shown to fear him as when she tries to explain it is not her fault for being placed in Class D However, he did not accept this excuse and tried to assault her until Kiyotaka intervened. Manabu voiced his surprise that she made a friend and derided her words after she said that it was not the case. In Episode 5, she is nervous at his presence at the hearing for Ken Sudō and is unable to speak until Ayanokōji tickles her and she regains her resolve. Despite her strong speech and determination in the case, Manabu is not impressed and continues to not expect anything more from her.

Kiyotaka Ayanokōji
Suzune is the first person that Kiyotaka interacts with when entering the school. He first caught notice of her when they were on the bus after the witnessed Kikyō Kushida trying to persuade Rokusuke Kōenji to move from his seat to no avail.

They formally meet when she inquires as to why he was looking at her as he stated he saw a similarity between them in the bus incident. She tells him not to compare them as she choose not to involve herself in such trivial manner as he notes she is worse than him. They are later shocked to learned they are classmates which Suzune states was a bad coincidence after they seated next to each other.

After a few days in class, they appear to get along since they are both loners who barely associate with their classmates. It was noted by Kushida that Kiyotaka is the only one in the class that Suzune interacts with. Indeed, they appear quite close as when he notices her about to be assaulted by her brother Manabu Horikita, he quickly intervenes. When she cries out to him to stop, he notes on the sincerity in her voice which he never saw in her while she watches in awe at him nimbly avoiding her brother's attack. After her brother hints that Kiyotaka is more than he appears to be, she herself begins to inquire about him only to receive vague answers. Later on, Suzune once asked him about his spending time with Kushida with a hint of jealously in her voice to his confusion.

Kikyō Kushida
Because of her goal to be friends with everyone, Kikyō has tried to extend this to Suzune but fails in the end due to the latter's disinterest in friendship. Kikyō once tried to enlist the Ayanokōji since he was the only person that Suzune spoke to everyday. Kikyō explained her plan was to meet with Suzune and be friends though Suzune saw right through it and rejected the offer once again.

Unknown to Suzune, Kikyō harbors great contempt for her cruel and antisocial ways as shown in Episode 3 where Ayanokōji finds her throwing a tantrum and cursing Suzune's name. However, she appears to want to hide this revelation from others as shown when she threatened Ayanokōji to keep quiet about the incident.
