Can't I See You One Last Time?

"Can't I see you one last time...?"
Those words repeating over and over in the mind of Tomioka Giyuu. Who is 'you', you may ask.
Well...
'You' was Giyuu's beloved. No, beloved isn't the right word. The reason being is, Giyuu never confessed. Why...
Why was one of the strongest people in the Demon Corps, Tomioka Giyuu, not able to confess?
Was it because he lacked the confidence?
Was it because he believed 'you' have enough on his plate caring for of his sister?
Was it because his, so called, friend always told him people didn't like him?
No, those where not it. Those were not the reasons Giyuu couldn't confess. You see, Giyuu was facing a bigger problem. That problem is...
The 'you' we've been talking about is dead. The person Tomioka Giyuu held close to his heart had died. Who is this 'you' person I've been telling you about? Let me tell you...
'You' is none other than the Sun Breath user,
Kamado Tanjiro
