it's all fun and games watching an anime just to see cute boys playing volleyball and getting character development until you get into fanfiction and ends up crying about this one for the whole second half.

ANOTHER REVIEW I HAD YET TO WRITE. okay so this is a kuroken au where on your sixteenth birthday, the last words your soulmate says to you appear on you skin, and in their handwriting. it's basically about kuroo and kenma growing up together as soulmates and then... kuroo get sick and dies neheheheheh. when it comes to mental stuff i'm a masochist, i love reading/watching stuff that will rip my heart into lots of pieces and i for some reason enjoy all that pain and if i cry then i tell the whole world. i'm weird like tendou just don't mind me. also they were kissing literally every five seconds SHIPUUUUUUU. yeah you guys should read this.

I never read Soulmate AU's, but this one TORE MY HEART OUT AND I LOVED EVERY. MOMENT. OF IT. You must read this. I don't even care if you are in the Haikyuu!! fandom or not, get the basic dynamic of the characters and GO READ THIS.

In all seriousness, most of the fanfics I read are just for fun. Although the fanfics I read are very meaningful to me, not many hold a deeper reason for me to re-read them other than "it's fun, well written, and interesting". This one, however, I will re-read because I felt that when I was done, I had actually learned something meaningful. This fic moved me in a way that not even seeing my favorite character DIE has been able to do.

I won't go on anymore because I don't want to give away any spoilers, but trust me when I say that you will NOT regret reading this.


Have a nice day <3

Ah, would you look at that? After months, I finished something. Also, what's wrong with Haikyuu fandom? Don't y'all like canon happy endings???😭

I am emotionally broken. I made the mistake of reading this right after reading “in another life” I don’t think there is a tear left to cry

I don't usually cry when I read but when I tell you that I cried, I properly wept. Anyways I'm too scared to read it again because I'll most likely just cry because of the post-it note scene.

This piece of work has wreaked havoc on my life! The sadness is indescribable GOD IT HURTS SO MUCH.

The depression is palpable and I hate how much it destroyed me but at the same time I loved it so so so much. The tears weren't stopping, my eyes were stinging like I poured acid on them, I felt like throwing up from the amount of pain and I cried so hard that I got a nosebleed. So yes, I can say with confidence that this fic has caused me not only emotional but also physical pain.

Thank you, @/cosmogony, I am forever grateful for this experience and I will never be the same again.

Agradezco infinitamente la existencia de esta historia.
Lloré y recordé mi trauma con otro fanfic de haikyuu (in another life). Disfruté de los momentos lindos y de verdad lloré mucho.

Sé que es un fanfic pero no pude evitar sentirlo en el alma cuando haikyuu y sus personajes son de las mejores cosas que me han pasado en la vida.

¡Qué bonito y triste es el amor!
Los amo mucho, kuroken.

It was great. I would totally reread it even though it made me cry extremely hard. I knew Kuroo was gonna die but the way it still gave me hope was mindblowing.

I can't even explain how much I cried while reading, it broke my heart completely. I think I never cried so much while reading something and I've read a lot in my life. As a super Kenma kinnie and simp, imagining him crying just broke me even more.

my heart.
my poor heart.
this book is so beautifully written. the vocabulary, the perspective, just the author's style of writing is all so perfect.
i think i could get drunk on the amount of tears i cried when i read kuroo's letter. the thought of chaotic kuroo being so soft for our sweet kenma makes my heart shatter. the slow change of dynamic when kuroo's in the hospital was probably the sweetest thing ever. to see kenma being so careful as he was with kuroo was heartbreaking.
to watch kuroo slowly die was a kind of pain i didn't know existed. i thought it was bad enough having to be inside kenma's head for the entire story, but having bokuto cry was probably the worst part of the book. the chaotic, crazy, happy-when-he's-not-in-emo-mode bokuto crying absolutely broke me. i think this is probably one of the saddest things i've ever read.

This is a fanfiction about Kuroo and Kenma. On your sixteenth birthday, your soulmate's last words to you get embedded in your back. Kuroo and Kenma are childhood friends, and they're meant to be. Kuroo's last words were "I love you" and Kenma's last words were "Please don't leave me." It was obvious, Kuroo was going to die before Kenma. They began to date when they find out they're each other's soulmates. After 5 years, they're living together, and were planning to get married in the summer. Kenma ran a successful gaming company, while Kuroo became a college TA. (teacher assistent) They were very happy, until Kuroo gets this genetic disease he got from his dead mother. ASL. A deadly disease.

HOLY FUCK! DO YOU KNOW HOW MUCH I CRIED IN THIS?!?!? MY HEART LITERALLY YEETED ITSELF OUT OF THE WINDOW! AND TO MAKE MATTERS WORST, MR LOVERMAN WAS PLAYING ON LOOP THAT WHOLE TIME I WAS READING IT! IN A FEW MONTHS I PLAN ON READING THE STORY AGAIN JUST BC I LIKE ABUSING MYSELF! LIKE I- I- I JUST CANT! THUS BROUGHT SO MANY TEARS, AND SO MANY SOBS!

this was truly an amazing story, gorgeously written, but why did you have to tease us with the fluff at the beginning and then drown us in our own tears at the end?

I have never watched a single episode of Haikyu!! nor have I read the manga.
This is my second fanfic from this fandom and I genuinely had no business reading this at 3am.

The Galaxy Is Endless (I Thought We Were, Too) follows Kenma and Kuroo in a soulmate AU where the last words your soulmate will say to you appears on your body (in their handwriting) on your 16th birthday. The fic starts off with Kenma seeing the words "I love you" on his collarbone in his best friend's Kuroo's handwriting. Although he is scared of the thought of those being Kuroo's last words and the future of him dying, he quickly goes to Kuroo's house and they start dating. The rest of the fic follows their life together.

This fic was written so beautifully. I loved seeing the relationship progression of Kuroo and Kenma and how they transitioned from high school to university. Their relationship was so pure and they had so much love for one another. I don't tend to read or like soulmate AUs, but this one was so well written and made me truly adore the relationship that Kenma and Kuroo had with one another.

Throughout the entire fic I was waiting for the other shoe to drop and literally had a feeling of dread while reading it. I saw the tags and the MCD warning but honestly nothing could've prepared me for the latter half of the story.

I honestly did not expect to start crying while I was near the end though, especially because this is the first time I cried while reading a book.




Overall, this was such a heartbreaking and beautiful story, that I didn't expect to cry for.
5/5 stars ⭐️

creo que nunca voy a volver a tocar un fic de Haikyuu otra vez...

Es el primer libro que toco para empezar el año y claramente tenía que terminar hecha mierda emocionalmente. Fue un libro al que entré con miedo porque ya leí In Another Life y nO SALÍ BIEN DE AHÍ, todavía me duele de pensarlo, y tampoco salí bien de acá.

El inglés nunca fue mi fuerte pero fue un libro fácil de leer y de entender más allá de que no estoy acostumbrada a leer en otro idioma que no sea español. No voy a poder ver las estrellas de la misma forma a partir de ahora, cuando las vea me voy a largar a llorar 😭
Mi hermana se levantó a las cinco de la mañana y me preguntó si estaba bien Y NO ESTABA BIEN, VENÍA LLORANDO HACÍA UNA HORA😩 no fue buena idea leerlo a la madrugada.

Me gustó mucho, nunca me voy a cansar de estos fics pero hay que frenar un poco antes de que me lea otro que me dejé hecha mierda. Me gustó que haya sido el primer libro del año <3

CÓMO SE ATREVEN A JUGAR CON MIS POBRES SENTIMIENTOS!!!! AAAAAAAA
Me gustaría decir que este libro me hizo feliz, pero en realidad solo destruyo mi pobre corazón y lo lanzó a la basura. Amé cada detalle en la personalidad de Kenma, como madura y crece por el pasar de los años y se va abriendo poco a poco a Kuroo por el simple hecho de amarlo; se siente tan real y hermoso. Por otro lado Kuroo... aaaaa ese hombre fue lo mejor del libro!, su personalidad y amor por Kenma son tan únicos y realistas que no podía dejar de pensar en lo hermoso que era.
Aún así el final con la carta y la caja de "I love you" de Kuroo fue simplemente desgarrador, me rompió el alma y se llevó algo que jamás podré recuperar.

I hold this fic very dear to my heart as it was the first fic I ever read on ao3 along with “In Another Life”. Every so often, since the first time I read this fic, I reread it as one does. It has never failed to make me cry, much kudos to the author for that. I’ll admit, I haven’t actually read or watched very much or Haikyu, but have dabbled in the fandom nonetheless (aka read probably hundreds of fics, looked at fanart, etc. lol) Idk why I made this review I just wanted to I guess. If you’re looking for advice on whether to read it or not, totally go for it!!! Just make sure to grab some tissues just in case :’)
