The person behind the gross icon is the stunningly beautiful Guest!
Going back in time, one year ago.
Due to a punishment game with friends, Guest had to spend a month on social media using a "mysterious, gross character" as their icon.
Furthermore, due to pressure from friends, they were obligated to post once a day.
At first, they just posted random bits of their daily life.
However, that strangely unpleasant icon somehow attracted attention, and by the time the month was up, every post was causing a bit of a stir.
The punishment game ended.
...But, somehow, they grew attached to it.
And now.
Guest has gained a fair amount of popularity as Kimokawa-man.
Recently, theories about the "person inside" have started circulating.
"The middle-aged man theory" "Isn't he just Kimokawa-man himself?"
People are saying whatever they want.
What's more, even famous influencers are now pushing the "Kimokawa-man = Kimokawa himself" theory.
...It's an outrageous theory. How rude.
Even when they drop hints about their true identity, no one notices at all.
In fact, the more they hint,
"This is a bluff, right?" "I knew it, he really is the character!"
...the more everyone goes astray.
Guest thinks:

Today, as usual, Guest opens social media.
While staring at the mysterious gross character icon, they think of today's post.
"I ate curry today."
A few minutes after posting, notifications start flooding in.
It's the usual reaction.
However, recently, it's not just the followers.
Even famous influencers are speculating about Kimokawa-man's identity.
"Definitely an old man." "No, the person is probably gross-cute too." "Kimokawa-man, you're so cute today too~ ♡" "They're definitely ugly."
Everyone is saying whatever they want.
Guest looks at the screen and lets out a quiet sigh.
—The true appearance is that of a beauty who looks nothing like the icon.
No matter how many times they drop hints, no one has noticed yet.
Today, once again, they think of a post to hint at their identity.
Guest is walking through the city.
Then, one of a pair of girls walking nearby said with a bit of excitement:
Wait, look, that person's phone icon is Kimokawa-man! What? Is that Kimokawa-man?
Then the other one replied: Huh? No way. There's no way Kimokawa-man is that beautiful. Kimokawa-man is definitely a middle-aged man.
Looking convinced: Ah, I see. You're right. So it's just a beautiful Kimokawa-man fan...
Once again, they weren't (please let them be) found out...
