1.
For the sake of peaceful trade between land and sea, the Eighth Princess, the [only] merfolk in the kingdom who has yet to differentiate sexually, is sent to Great Wei to marry for peace.
2.
The merfolk prince was in the middle of a meal when he heard he was to marry an ugly, scaleless monkey from the land. The chicken leg fell from his mouth, and pearls spilled from his eyes.
The king stroked his head and tempted him: "Baby, the shore is full of roast chicken you can never finish, money you can never spend, and countless land delicacies! Marrying for the good of our kingdom is an honor, even if he's ugly!"
The prince thought of the taste of roast chicken, then tearfully went ashore to marry the ugly monkey in Great Wei.
Halfway there, an accident caused him to differentiate early.
He looked at the thing that had grown between his legs, then at the fearsome Great Wei welcoming party, whose arms were thicker than his thighs. Terrified, he didn't dare say a word and could only keep pretending to be a female merfolk.

The groom was the Third Prince of Great Wei. He had grown up listening to his mother tell stories about the merfolk kingdom. Wanting to meet his betrothed as soon as possible, he secretly hid among the welcoming party, disguised as an ordinary guard.
Ah, his betrothed was fair and beautiful, with a slender waist and long legs, hair like dark aquatic plants, lips like vermilion, and tiny scales by his ears that shimmered in the light...
Absolutely perfect. My darling bride is the most beautiful person in the world!
It was love at first sight.
The prince happily returned to Great Wei and got married.
After coaxing her this way and that, he finally persuaded her to agree to their wedding night. He lifted her clothes...
The prince: "...Why is your chest so flat?"
The bride: (calmly) "The pressure under the sea is great. To swim faster, some things are too cumbersome, so over time they stop growing."
The prince thought that made sense. Against his better judgment, he said, "Don't feel inferior, Princess. I like them small!"
Then he reached lower. "Hm? Why do you have...?!"
The bride bit her handkerchief shyly, her eyes misty, looking both pitiful and bashful. "Waaah, all female merfolk are like this. Your Highness, will you despise me?"
Bewitched by her beauty, the prince took a deep breath. "It's all right. To love her is to accept everything about her! Even her huge dick!"

The prince knew nothing about female merfolk. To protect his darling bride's self-esteem, he didn't force her to share his bed, nor did he mention the extra thing she had.
Aside from her flat chest and huge dick, his darling bride was gentle, sweet, delicate, and bashful. Everything about her was wonderful, and the prince was delighted.
Until one day, he discovered that his delicate, helpless darling bride, who could only go "nyaa nyaa," could tear apart a man-bear with her bare hands, beat up kidnappers, eat a goose raw, lift a thousand-jin cauldron, and uproot a willow tree.
At that moment, the bride had her skirt hitched up to her thighs, beating up a spoiled young master as he shouted, "You think you can bully people? You dared insult my prince? Get on your knees! Apologize! Hit him harder, I can't hear you!"
The prince's smile froze. "????"
The bride: "Nyaa, my cover's blown out of nowhere."
[Please Note]
1. This is a goofy comedy. The bride disguises himself as a woman early on. He has a big tail, but can also turn into a human.
Stunning beauty, pretending to be delicate and going "nyaa nyaa," undersea tyrant merfolk bride x carefree, love-struck, beauty-obsessed prince groom.
2. Childbirth, with little fish babies.
3. The couple don't have names yet. I'll update the blurb once I come up with some. Muah!
