a/n: Requested by Eon_starx, Okay Here is a Cheater Yandere, So... Yeah, I'll just use my OC here so I picked Joan Heartfilia (Future) if you don't know who that is here's a picture... Remember This is the Kingdom of Azure

*2nd Person's POV*

You were walking towards your girlfriend's house, since it was a weekend you wanted to ask her out for a date since she has been very distant from you, when you got to her house you opened the door no one was there you checked the living room, kitchen backyard the results are the same she wasn't there

You went upstairs that's when you are in front of Joan's room the door is slightly open, you look through it she was on the bed with a man beneath her while she is on top of him, they are making out

You opened the door and slammed it closed, they heard it and looked at it then the two saw you, she pulled away from the man

Joan: [y-y-y-y-y/n], I can explain

[y/n]: I'm gonna stop you there... *You look at the Guy* You Asshole

Guy: Y-yes sir.....

[y/n]: Get out or I'll drag you out of life and into hell

The guy wan as fast as he could, you return your focused on Joan.

[y/n]: Now... Joan... Explain...

Joan: I... I wanted something more.... But you were just so busy, I have needs [y/n].... I wanted our relationship to move on to the next level but you never even thought about it....

[y/n]: That's not true... Maybe I was waiting for us to get married because it will make our bond stronger!!! I wanted us to be inseparable, so I wanted to wait a few years to propose to you!!!

Joan: [y/n]... I-I'm sorry...

[y/n]: Save it... I guess the bond that we forged aren't strong enough for you to resist the temptation... Maybe it's best that we go our separate ways

Joan: [y/n].... Please, no no.... I don't want to lose you

[y/n]: You already did...

You went out leaving Joan there crying...

*Joan's POV*

He left me.... Was it my fault? NO it was not... It was that man he tempted me at my weakest, but this time I'll make things right... I call the man on my phone and meet me at the hotel down town, he agreed, I grab my knife and hid it in my skirt

Joan: Don't worry [y/n]~ I'll fix things between us~ I will make sure nothing ever comes between us...

*2nd Person's POV*

You walk towards Augustine's house, you knocked on the door instead of Augustine answering it it was his sister Dianne Hiryu (a/n: This is Future Dianne)

Dianne: Oh [y/n]... Hello there how are you?

[y/n]: Good afternoon Dianne, I'm fine how about you?

Dianne: I'm great come in...

[y/n]: Is Augustine here?

Dianne: Oh he's out shopping, are you thirsty? I could make us some tea

[y/n]: That would be nice

Dianne: Alright...

When she came back and poured you some tea, you sip some of the tea she made, she start another conversation

Dianne: So why are you looking for Augustine?

[y/n]: I was just wondering if he would hang out, but since he's out...

Dianne: [y/n] is something wrong?

[y/n]: I... Don't want to talk about it...

Dianne: [y/n] you are like family to me... You can tell me anything, if there's something in your heart that is bothering you, tell me

[y/n]: It's about Joan...

Dianne: Huh? Something happened between you?

[y/n]: I caught her... Making out with another man earlier today

Dianne: Oh!... I'm sorry about that

[y/n]: Don't worry I'm fine...

She stand up and went to you and envelop you in a warm hug, you could feel your tears threatening to come out

Dianne: Sssshhhh... It's okay let it out... I'm here for you

You return the hug rather tightly I might add, and let out a sudden scream, you sob on her shoulders for a brief moment until your sobs get weaker until it was all gone

Dianne: Better?

[y/n]: Yeah, Thank you Dianne

Dianne: it's no problem... Glad I Big sis could help

The door opened revealing Dianne's brother, and his friends; Alex, Tatsuya, Rose, Liza and Cynthia

(a/n: Top to bottom order: Rose, Liza, and Cynthia. They are their future appearance, sorry there are no Pics for Augustine and the other males, since there are no Avatar maker for boys)

Dianne: Welcome back little brother

Augustine: Yup... Oh hey [y/n], what's up?

[y/n]: Hey man...

Rose: You okay? Your eyes are red

Dianne: Don't worry I will explain, take a seat

Timeskip after explaining

Augustine: Oh my God I'm sorry man...

Alex: Yeah.. Sorry about that

Rose/Liza/Tatsuya: *Nod*

Cynthia: ...

Rose: Cynthia?

Cynthia: So you found out huh?

[y/n]: Wait... You knew!?

Cynthia: That's right....

You stood up and grab her by the collar

[y/n]: Why didn't you tell me sooner!?

Tatsuya: Now [y/n], calm down man...

[y/n]: DON'T TELL ME TO CALM DOWN TATSU!! ANSWER ME!!!!

Cynthia: If I did.... Would you believe me?

[y/n]: ....

You let go of her, and stepped back she looked at you with tears in her eyes, you felt bad at yelling at her so you just hugged her

[y/n]: I'm sorry... I didn't mean to shout

She hugged back resting her head on your shoulder

Cynthia: It's fine.... I'm sorry if I didn't tell you sooner

You both pulled away from the hug, you all played games and have a good time with your friends.

Timeskip

You walk home from your friend's house you all took a group picture since it was a long time since you have saw Tatsu and Alex. When you are in front of your door you put a key in the doorknob but when you turned the key...

[y/n]: Weird did I forgot to lock the door?

You opened it when you went in you slipped causing you to fall on your butt, you look at the thing that made you slip, it was a red substance you realize it was blood, there is a trail you followed it, when the trail ended it was in your room, when you opened it you switched on the light and saw a gruesome sight... It was the man from before, the door then closed and a click was heard meaning it was lock, you look at the person who locked it

[y/n]: Joan!?

Joan: Hello there boyfriend~

Her eyes were dull and she has blood all over her clothes, but the most creepy sight you saw was she was smiling, it was not her usual smile it was a psychotic one

[y/n]: W-what did you do!?

Joan: Simple, This man is in the way of our love

[y/n]: Love? LOVE!? You cheated on me... With the guy you just killed it wasn't his fault it was yours!!!

Joan: No!! I am not at fault here... It was him he was in between us!! I won't let him or anyone get in out way!! You're MINE AND ONLY MINE!!! HAHAHAHAHAHAHA!!!!

[y/n]: You're crazy I will never be yours!!!

Joan: Oh [y/n]~ I want you all to myself... Even if I have to murder everything that stands in the way of our love~

You run at her but she tripped you, you felt something sharp on your neck, you feel your world slowly fade away

Joan: Don't worry [y/n]~ Once you wake up we will make love~

a/n: And that's it... Hope you all enjoyed it....
