(Ruikasa) my dead dear

Where it all started

Tsukasa's pov :
I woke up to hearing Saki screaming at me to wake up .
Saki: ONI-CHAN WAKE UP WE ARE GANNA BE LATE FOR SCHOOL . Saki screamed at the top of her lungs while bursting the door open
I groaned as I asked saki
Tsukasa: what time is it?
Saki: ITS 07:50 AM WE ARE GANNA BE LATE HURRY UP .
I hurried out of my bed and went to wear my uniform , i grapped my lunchbox and saki also grapped hers , we ran out of our home as we screamed goodbye to eachother loud enough to be heard and hurried over to the opposite direction.
I finally were at my school gate , i saw rui talking with nene , i walked torwards them .
Rui: Tsukasa kun you are very late this year must be a sign~ haha . Rui said jokingly . I was barely catching my breath until the bell rang i could not even have time to breath!! Stupid bell I thought to myself , before i was about to go to my classroom rui stopped me and told
Rui: lets eat our lunch at our normal spot today i have something to tell everyone. Said rui he rather looked happy I nodded and went back to my class.
After hours of learning it was finally lunch time i grapped my lunchbox that saki made i know i have the best sister ok we are out of of point but i ran to the rooftop i was excited to see what rui would say . I opened the door to the rooftop to see nene and rui already there waiting for me sadly emu couldn't sneak out of her school today .
Rui : oh hey tsukasa kun come sit beside me i have something exciting to say!
Nene: tell us already rui ! I been waiting ages !!
Rui : i got a girlfriend! Rui said while smiling nonstop.
But in the other hand Tsukasa excitement faded hearing that as if his world just shattered.
Ruis pov :
I have just told my best friends i got myself a partner !
Rui: her name is mizuki i think you guys already know her becuase she is a friend of Ena , I'm so happy i had a crush on her since middle school .
Tsukasa : she was youre friend in middle school?..
i felt a bit worried for tsukasa when i heard his tone of voice he was a bit more quiet than before but nene asked me questions non stop questions that i just thought it was due to tiredness and didn't think anout it .
Tsukasa suddenly got up and said
Tsukasa : I-I need to go to the bathroom ..
He started running away i felt a big worried so I decided to follow
Rui: i will be back nene wait a min
Nene : boo im all alone
Tsukasa pov :
I ran to the toilet and went inside one of the stalls, i didn't know why i felt such emotions i am supposed to be happy for Rui as his friend but why, why am i feeling so sad . As i thought to myself i was right about to cry until i heard a familiar voice , it was Rui!
Rui: tsukasa kun are you in okay? Im worried for you , you've been very quiet is something bothering you? Rui said in a worried tone . I didn't want to let rui know about how i was feeling so i just started acting.
Tsukasa: OUCH MY STOMACH!! THIS IS SUCH AN UNLUCKY DAY! I shouted
Rui pov:
Right when i heard tsukasa say that i knew he was alright the reason he was so quiet was due to an stomach ache .
Rui: do you want me to bring you some pills from the pharmacy room i could ask the nurse?
Tsukas: don't worry rui! But could you get out its a bit embarrassing!
Rui: oh..alright then don't be too late for class . I said while leaving to got back to nene
