"Yooo,tanjiro!i'm back~" you greeted
You're friend,tanjiro as you run up
To him.

"Ooh..welcome back,(y/n)-san!how's
Your mission?" Asked the
Dark red-haired boy as he smiled
Gently at you,and he earned one in
Return "it gone well,so far!say..tanjro,
Have you seen inosuke this morning?
I..didn't see him earlier too." Tanjiro
Tensed as he heard that filthy name
Coming from your mouth

He was happy to know you say his
Name more than three times,now...
You gotta say another man's name?!
He felt anger rise up in his body but he
Remained his composture as he calmly
Answered to your question "no,not
Really..i also haven't seen him." You
Scratch your head confused "huh.?weird.."

"Yes..indeed.but,we'll look for him!
But for today,wanna go eat sime soba?i know a nice stand here near by!"
Seeing a cute smile form in your face
Made him blush,you nod and you two
Ran off.

Sitting on a bench you happily slurp
The noodles not noticing the lovesick
Gaze the boy beside you...staring at
You like you're the most beautiful
Thing in the world.he just loved these
Moments he can stare at tou freely,
Well,it's not like it's the first time he
Did but that doesn't matter as long as
He can stare at your beautiful face
All day long.

"Ah,(y/n)-chan is that you..?"

"Hmm..ah..ah!Tarou-San!"

Your friend smiled and you stand up
From your sit making tanjiro widened
His eyes as he saw you hugged a man
He doesn't know.why...why did you
Leave for that..bastard.is that your
Childhood friend?

Does that mean he knows you better
Than him?!Do you...love him?!?

Wild thoughts were going feral in his
Mind as you smile at the man you
Claimed to be your friend,he doesn't
Want you to smile at that man,you
Should be smiling to him,not him.not
Inosuke..not anyone else..

Looking blankly at the man weak at the
Ground,bloodied up as the man begged
For his life.a broken arm,a bruised
Face and his leg bleeding.the man
Sobbed as he clenched his fist,begging
Him not to be killed

"Please!please..i..i don't want t-to die..
Pl-..i-i'm begging you.."

Tears are running over to his cheeks
But tanjiro's blank face didn't change
As he didn't give a single damn about
This man's life,he tried to steal you
Away from him.it was his fault Anyway..so why should he spare him?"

Lifting his katana up,the man's eyes
Went wide as he saw the blade high
Above his head,and there goes..on a
Swift swing to his head,a single tear
Left the man's head as his final
Thoughts remained in his head

'(Y/n)....i'm sorry..'

Blood splattered on tanjiro's clothes
As he decapitated his rival's head clean
Off his body.the rolls off as blood spilled
On the grass and trees,everywhere.

Buy alas..at least he's gone.

A snap of a twig was heard and he
Saw you,trembling in sight of the dead
Body he just murdered..for you.
He gives you a twisted smile and you
Shivered.walking towards you as you
Remained frozen he caress your cheek,
Blood was painted in you're cheek
As you hear him whisper

"You're safe now...my sunshine."
