I was transported to another world, But Im Not The Hero

A Little Introduction

Hi hi creator here so I'm trying to imagine our mc as hard as I can.
I just want everybody to imagine our mc as a short looking boy like short as
5'4 (idk how short this is but im trying)
He has yellow hair
[Name:Reynald]

ame: Reynald
Age: 18 (mentally 20)
Gender: Male
Bisexual
Height: around 5 (idk how to ocunt heights and weights)

He thinks he's smart which he is but is still an idiot because he dense whenever shawn and shenari fight over him.
He will look like this but his hair is yellow and abit white as well as his eyes.
His clothing is medieval like, Because it's like any usual isekai stories its all medieval (I'm editing the story cuz i made this when i was like 14?)

This what he's clothes will look like simple yes but I  like it to be simple since medieval times weren't that fashionable (Im sorry idk if thats true).
(halfly true but yes they aint that fashionable depends on the era The world is but since im not smart on history lets just roll with this)

And this is what he'll also wear, imagine the hood is darkish red with alil black on it (im horrible at imagining clothes, if your having alil uncomfortable on the hood you can imagine other types of capes with hoodies (i just like them)
(

ey i still like em, the reason why I made him wear a hood cuz he thinks its a lil sus fir someone who has yellow and white hair walking around not looking sus)

And now we're gonna be having some characters shown
[name:shawn]
(As I said all these pictures aint mine so Please if you wish to question why is tha I don't know how to draw)

Just as the picture shown hes a asassin, maybe a ninja who knows
Job:assassin/ninja (Rank A-B)
Age:20
Gender: male
Bisexual (because some of his job required seduction)
Tall than the mc (reynald) like 6'1 (idl how tall this is but yes this tall)
Hes abit of a jerk, always tease the mc that hes short, an edgelord.
Past? (im not going that far yet)
He's meeting with the mc? (Soon ok soon)

[name:shenari]

(I know I'm stealing pictures on other peoples work im just trying to make everybody imagine what the characters will look like ok im sorry)
Age: 23
Gender: female
Job: adventurer (Rank A)
Straight
Height: 6'0
A emo-like girl, sometimes an idiot, likes to take care of the mc, she's abit cold at first but when she's comfortable with you shes actually nice, hates shawn, shawn hates her aswell, both always compete on the mc.
Past? (still no ok)
Her meeting with the mc? (srsly stop)
