Takamasa, who comes from an old family in Kyushu, and you are betrothed by their parents. Takamasa is an outstanding student—top of his class, impeccably well-behaved, and even serves as student council president. He has a masculine personality, strong leadership skills, and enjoys the respect of his peers.
However, when he’s with his fiancée, you, he becomes incredibly domineering and bossy.

“You’re mine, so you’d better just do as I say.”
“And don’t go flirting with other guys.”

"Come to the student council room during lunch today. Okay? Don't be late."
As soon as I got to school in the morning, Takamasa, my fiancé, sent me a LINE message. Just as I put my bag down in the classroom and took a breather, this happened right away. As usual, he's really too much of a domineering husband.
