Different Feelings (Yandere-chan x Male Rivals)

Week 1 Arc 1- Not Bad at All

Week 1- Day 1
Rival???: Osano Najimi
As I walk up the stairs, about to chase Senpai to see him, I bumped to the "new guy".

"Hey watch out!" His Vermilion eyes darted on me. I went to apologize, but his tsundere attitude made him only respond "tssk, watch your steps young lady, so you wouldn't stupidly bump on someone again."

That boy! Who do he think he is?! Damn if I could only kill him, but I don't have enough reason to kill him though. It was my fault too anyways.

At least I saw Senpai. His plain black eyes, clean hair that is perfect with every strands, his smile, aaaaaay! I'm contented at the time.

When our class started, our chemistry became hard for me all of a sudden. I could still handle it though.

Lunchtime, ah! Time to see Senpai again. I went upstairs to see him, only to be faced by no other than Osano Najimi.

"You again? Seriously are you stalking me or something?" Wow, this guy assumes too much. It's getting ridiculous.

"Or something. Thanks for your question. No, I'm not stalking you for the Akademi's sake." I eyed him coldly hoping he would get my look, but he just humphed and walked away. Then that's when I saw Senpai following.

"Ah, sorry for my friend, he is just like that. You are miss?" He said as he would like to ask my name. Which is a miracle, considering he never actually notice me in a good way back then.

"A-ayano. Ayano Aishi." I responded, damn did I stuttered.

"Well it's nice meeting you. Everyone's calling me Senpai, but I'm Taro Yamada. Pretty generic name if you would say so I understand if it's funny."

"No it wasn't!" I accidentally raised my voice. Oh I regret that. "I mean, it's kinda awesome since you know, it's like... A traditional name! Yeah..." I scratched the back of my head. Speaking of a high school girl eh.

"Wow, it was a first. No one actually appreciated my name. No wonder why Osano's looking at you." He laughed which made me confused.

I turned around finding that Osano is actually staring at me but quickly looked away. I saw him looking thanks to my yandere instincts.

"Are you done now, Senpai?" Osano asked and spitted the name "Senpai" like it's a dirty word.

"Heh, you still call me that? Doesn't suit you." Senpai mockingly said. With him smiling, I can tell he is indeed happy. And I'm one of the reasons why he is happy.

Senpai walked downstairs but turned around to look at me. "Hope we'll see each other again." Then he walked beside Osano.

Maybe this whole new gameplay isn't bad at all. I feel like I'm floating through clouds and, in love!

Ring!

The bell rang, time for afternoon classes. I didn't even listen, I kept daydreaming about what just happened a while ago.

Chemistry class

The formulas are to complicated for my liking. I can't even understand a single thing. I just held my pen shakily and not even writing anything.

"Aishi, please tell me if you can't understand a thing." Sensei insisted to instruct me. I think I might actually need a...

"You might need a tutor from seniors." She continued my thought. Oh gosh, I will be tutored by seniors. I just wish it will be senpai. Please let it be Senpai.

"Please stay after class so I could introduce you my previous student who excels in this subject. He could teach you for sure." Sensei looked to me, an assuring look in her eyes. She did say it's a he, so this could be Senpai right?

----

It's now after class, yet I stayed as Sensei told me to. I just hope this will be Senpai, please let him be Senpai.

The door now opened, the teacher came in but motioning the said tutor-student to stay outside first.

"I would like to introduce to you your tutor, please meet--" my eyes shined brightly in hopes it will be Senpai. OMG it must be him right? Pleasepleaseplease-

"Osano Najimi." W--what? My hopes shrank and I saw this orange-haired guy again smiling, eyes closed, greeting.

"Hi, I'm Osano Najimi. I'll be your tutor in-" he stopped once he opened his eyes because of me.

"Oh, it's you." He suddenly put that cold attitude back. Well, isn't this going to be a long day?

A/N
This is my first fanfiction I'll ever write seriously. Hope you guys enjoy my headcanons. I can't think of Yandere Simulator subjects that are difficult, so I just went with Chemistry. I mean, Chemistry is a bit hard right? That's why you can't match with your crush T-T ... Wait that's different and off topic lol. Don't mind me...
