Concept: Not every rival loves senpai

Not every rival loves senpai!! Sounds weird but hear me out.

Yandere-Chan is deranged and only wants him. We know she is Yandere. She will go after anyone that hangs out with him / rips him away from her regardless of who they are. So, here's my idea. I've changed their stories slightly also to fit my concepts!!

Osana: Osana is a childhood friend of Senpai. She moves away and recently only moved back to the city. She goes to senpai's school and accidentily bumps into him..asking him for help in figuring out the school. She recognizes him, confesses that it's her and through the week regains her feelings for him. She confesses on friday.

Amai: Amai does not like senpai, senpai likes Amai. Amai will end up slightly falling for him but not enough to confess, senpai will confess to her on friday.

Kizana: Kizana is too stuck up to like senpai. Senpai does not like her. She uses senpai for his money and slight popularity as a way to boost hers. Ayano hates this, so she decides to get rid of her. If you don't get rid of her by friday, she will continue to drag him further and further away from you.

Oka: Oka falls for Senpai the same way that any emo girl would. "He's the only guy that's ever shown me kindness, thus I am madly in love with him." She will confess to him on Friday.

Asu: Asu will not fall for Senpai but Senpai will fall for Asu. He likes a strong independent woman. He will confess to Asu on Friday.

Muja: Muja and Senpai are close friends. Muja will drag senpai away and probably might find you out as the killer due to her smarts. That's why you have to get rid of her.

Mida: Mida is a disgusting pedophillic monster that will destroy senpai's mental health as well as make him a victim. They don't like eachother but Senpai falls for her sexual nature.

Osoro: Osoro and Senpai don't fall for eachother. Osoro will convert senpai into a delinquent if you don't stop them.

Hanako: Hanako doesn't "LOVE" senpai. They are siblings. She will, however, stop him from being able to be in a romantic relationship if you don't stop her by friday.

Megami: She knows who you are. She knows WHAT you are and will stop at nothing to put you in jail. She doesn't "love" senpai. She just pretends to so she can get your attention enough to put you in jail.
