omfg ikr! Idc if it’s romance or bromance, there is something unexplainably there that can’t be defined at all. Without Hinata, Kageyama would never be the way that he is now. The same could be said about Hinata but for Kageyama, it just had to be Hinata. Everytime things got tense, Hinata called out Kageyama or reassured him without a moment to waste. I hope we get a chapter of them playing together again because my aching soul really needs that rn.
Also also, I think that the “I’M HERE!” is a reference to japanese figure skater, Yuzuru Hanyu. It was the first thing he said as soon as he finished his program in 2018 pyeongchang Olympics after a series or injuries prior that had brought suspicion of whether he was going to be able to preform or even attend at all. (He won)
“I’m here” can be translated from “Tadaima” - which means
-“I’m home” [this form of meaning is used as greeting when coming home to someone else in or at (your/their) home]
-“I’m back”
-“I’m (back) here”
Hence I think that it could be inspired or referenced from Yuzuru. Just a theory however

I ADORE Yuzuru!! And I know the program he did at Pyeongchang, I was so worried the whole time, given how he was injured so many times, and fell here and there or faltered in his landings. But. It was one of the most beautiful piece I've seen him perform.
And he did say "I'm here!" not only at Pyeongchang, but also that one time (shoot I forgot where) Javi had performed so good that when Yuzuru had a small falter in his program, the Spain fans around him started chanting "Javi, Javi" and he got so angry he modified his program mid-performance because he was so damn competitive hahaha. And later he was like was like "I'm HERE, you know!! (/TДT)/ " explaining to an interviewer, talking about how he got mad jealous of the Javi fanchants.
I'm sorry I just gushed about Yuzuru all over here lol but cmon this cutiepie legend deserves all the gushing in this world!

Omfg I’m sorry I didn’t reply quicker so that I could gush about Javi and Yuzuru and kagehina and everything!!! My damn mangago decided that it wanted to be a selective lil hoe who only notified me manga updates instead of thread messages. I have my own personal ship of javi and yuzuru ლ(´ڡ`ლ)...That’s for another time-
But yea, once again I can’t help but be in complete agreement with ya’! Yuzuru and Javi both have my heart and I cry everytime I rewatch Yuzuru’s interview about the earthquake that hit his hometown. Hell, I cry watching them smile, or cry to them crying themselves. I cry when they fumble their jumps or even when they first step on the ice. I’m just so glad that I found a fellow fujo-skater-stan fren~ It’s dope that you understood the reference too. Aww man I’m just really happy ig
Hinata's "I'M HERE!"at the end of the backstory just filled me up with emotions... like he was the answer to Kageyama's helplessness.
Take it any way you want--- platonic or romantic--- but Kageyama and Hinata are what complete each other. And they've been waiting their whole lives to meet each other, their other half. This is so much. A sports manga isn't supposed to mess with my feelings so much dammit
