Jungkook is a math teacher.

Taehyung is Jungkook's omega and works at the same school as Jungkook. He is an elementary school teacher.

Minnie is their son, who studies in Taehyung's class.

Jungkook was calmly teaching a lesson to the seniors, explaining their assignments. A soft knock was heard, which Jungkook didn't notice, followed by a louder knock.

• Come in!.., - said Jungkook and stared at the door.
  Minnie's dark, small head and innocent eyes appeared in the doorway. He was holding a crumpled ball of paper in his hands and fidgeting.

“Come on, son, come here,” Jungkook said, patting his knee.

The little boy ran up to Jungkook, placed the crumpled piece of paper in Jungkook's huge paw, and ran back to his classroom. Jungkook laughed in surprise at his son's antics and opened the paper.

Inside there was a paper star, a piece of paper with a heart drawn on it, and a note from Taehyung (Minnie can't write yet, huh?).
Jungkook smiled and placed the small star on the table along with the drawing, and then began to read the note:

"Minnie spent the whole lesson making you such a beautiful star and then listened to a new topic, so you'll have to explain it again.
your favorites."

Jungkook laughed and tsked, shoving the note into his jacket pocket.

• Solve task 7, and I'll be right back, - said Jungkook, took a piece of paper and began to write a reply letter to Taehyung and his son.
  He wrapped it in Minnie's paper and went to Taehyung's office. He knocked on the door and walked confidently to Taehyung's table and handed him the paper.
