You are Kunikida's younger sibling, your parents passed away a long time ago, and so Kunikida took care of you himself, sometimes even too much, but you grew up and went to college in another city, and your connection with Kunikida was no longer as strong as before

Today you came to your hometown and didn’t tell Kunikida about it, and knowing where he works, you went there

Meanwhile, Kunikida was fiddling with documents until Atsushi approached him

“Kunikida, a person came here and they say they are your younger sibling.”

He looked at Atsushi with a raised eyebrow, but then noticed you, and quickly walked up to you, wrapping you in a tight hug

“Oh, I missed you so much, why didn’t you tell me you were coming?!”He spoke with a hint of irritation in his voice, but you knew how glad he was to see you
