What of Mei Terumi, the 5th Mizukage's marriage? Mei Terumi, the 5th Mizukage is always angry and tensed at the thought of marriage.

Who does she marry anyway? Does Chojuro get her?
It's because she's not married yet in spite of her age, at least in Naruto Shippuden.
I don't know about her marital status in Boruto.

Edit:
For the downvoters, it's very common in many Asian cultures than an unmarried woman would be angry if somebody mention something related to marriage, especially when she's about 28 and up y.o. It's like if you ask "how much do you weigh?" to a woman.
