karma's birthday ^0^

bsd cross over

blood has many types, A B O and AB. in this world, blood type is a level of your life.
people with blood type A are the superiors. they are the one who's above anyone. they have the authority to control B, O, and AB. blood type B is the second one. they have the authority to control O, and AB but not A. O were the normal ones. have the authority to control AB but not the upper one's which means A and B. AB blood types are the lower one's they don't have any authority to control other blood types. they have a body that is always in heat so, they have a collar to observe their temperature. heat makes the other blood attracted to them and courage them to bite them in their neck as a mark. they also can't control their hormones so, they have the collar to tell them if they need to drink their medicine (to take down the heat). in additional when someone bites them no one can touch them than that person who marks them. and you y/n l/n is lucky to have blood type A but, you are living with a person with a blood type AB. he's karma akabane, your living with him for over 5 years. why?... your parents died when you are 10 years old luckily your parent's friend let you stay with them.

The AKABANE Residence, Mrs. akabane is a blood type AB and Msr. akabane is a blood type A. karma's parents aren't always their so you live with him and his little sister's shadow for over 5 years ( yup I'm on onii-chan's side this time ^0^).
his sister shadow was a 10 years old girl and a blood type A just like you so you take care of her. at first, everything was normal until karma reach his 15th birthday, and it's today. why again? because when a person with blood type AB reaches their 15th birthday. their heat will be no longer in control. meaning they need to start drinking medicine to make themself calm and its kinda difficult to control because the first karma is a boy. second, you and shadow are blood type A and a girl. meaning he might be in heat every time he sees you because your a blood type A and a 15 years old girl. so, your hormones are everywhere in the house that may trigger his heat.

Y/N'S POV
i was on my bed thinking about what should i buy for his birthday. "i had already bought him a watch yesterday as a Christmas present. now idk what should i give to him. ughhh this sucks why do that devil's birthday was on Christmas!. can't be other day so i have more time to think. ugh, i can feel my head is in smoke." i decide to sit on my bed and look at the time. "wow its already 10 am... i should go downstairs now."
you walk downstairs as you heard noises from the living room. as you expect its karma and shadow fighting.
" Aniki!! let me just play with your Nintendo! i just want to play the legend of Zelda!!" shadow begs while her brother is holding it up high. "No.. first of all, the legend of Zelda was not for children like you. second, this Nintendo was brand new and my gift from mom so i don't want you to touch it. and lastly, today was my birthday meaning you should obey me understood." karma explains as he holds it higher. yes, they are always like this. "*sniffs* i...i ... i just want to borrow it. *sobs*" shadow explains as she burst into tears. karma rolled his eyes then give him the Nintendo. "ughhh!! here happy?!" karma spite. you walk towards them to wipe shadows eyes and carry her. "karma she's just 10 years old.. just let her borrow it." you explain as he just turns around. "tch fine whatever". then he walks to the kitchen. you put shadow down as you follow him to the kitchen .
"cooking lunch already?" you ask. he looks at you with his furrowed eyebrow. "isn't that obvious?". you just giggles and hug him. "chill ok? anyways.. happy birthday." you greet him. then, you looked up to see his face and he's blushing. yup, you and karma already knew that you loved each other. he looks away and says "tha-thank you... I guess...." he mumbled. you can't help it but to giggle. "y/n you-you knows that its my 15th birthday right?" he asked. you buried your head on his chest. "yeah i know i haven't bought your gift yet." you explain. karma holds your shoulder and says "no not that ummm how can i say this...can i go to the bathroom real quick? its just my collar is so tight i just need to loosen it ok? " he asked. you nod as he rushes to the bathroom leaving you confused. "what happen did i do something wrong?" you as to yourself. then you realized what he just said. "wait do i? oh no gosh i'm being so clingy i haven't noticed." you mumble to yourself as you bury your face on your palm. you can feel your face turning red. " i i i need to say sorry to him.". you continue cooking. a minute later karma finally opens the door of the bathroom. you instantly grab his shoulder. "karma i really really sorry for what i did earlier." you beg as karma just tap your head. " don't worry its not a big deal." as he smirks. then karma walks towards the living room to get his phone. he dials a number and calls someone then walks outside of the house. you think its Nagisa so you continue cooking.
