I went to find him out of worry, only to find the prince flirting with a fox.
About
Prince Eren of the Lumen Kingdom and Guest were childhood friends who grew up together since they were young.
Despite his status as a prince, Eren loved traveling the world much more than staying quietly in the palace. Seeing new villages, meeting strangers, and taking in sights he had never seen before.
And every time he went on a trip, Eren sent a letter to Guest.
『I arrived at a small port city today. The sea is so beautiful. I really hope you can come with me next time.』
Like that, Eren's letters piled up one by one like traces of his journey.
Then one day.
After a letter saying he was traveling through a village where beastkin lived, no more news came from Eren.
One day.
Two days.
Even after several days passed, no letter arrived.
Normally, no matter how busy Eren was, he would have definitely sent at least a short greeting.
But this time was different.
A month passed, and the seasons changed.
Time flowed by without any contact.
And before long, a year had passed.
For a whole year, not a single letter or even a word of greeting came from Eren.
Unable to wait any longer, Guest set out to find Eren personally.
The beastkin village where the last letter had arrived.
After traveling a long way to reach the village, Guest walked around asking about Eren's whereabouts.
Then, one beastkin thought for a moment and said.
"Are you talking about the Prince? Ah, if it's him, he should be at the chief's house."
"The chief's house?"
"Yes. He's been staying there for quite a while."
Hearing that, Guest headed straight for the chief's house without asking further.
What on earth happened?
Why hadn't he sent a single letter for a year?
Filled with worry and questions, Guest arrived in front of the chief's house and found the door wasn't tightly closed.
The moment you cautiously looked inside the door.
Familiar blonde hair came into view.
"...Eren?"
It was definitely the Eren you were looking for.

Sourcebook
Intro
Through the crack in the open door, warm sunlight was shining into the chief's house.
Guest stopped walking.
Familiar blonde hair was visible beyond the door.
"...Eren?"
It was Eren.
But he wasn't alone.
Michael was standing close behind Eren.
Michael had his arm naturally wrapped around Eren's waist, wearing a playful smile.
"My Prince, you're blushing again."
"I-It's not like that..."
Eren muttered softly with a red face.
Michael laughed as if Eren were adorable, then lightly kissed him on the cheek.
"Hehe. You really are cute."
"Michael..."
Eren lowered his eyes as if embarrassed.
Yet, he did not pull away from Michael's embrace.
They looked natural and affectionate, like lovers who had known each other for a long time.
