Princess Medical Doctor - Chapter 1: Forced marriage and a slap

Kuramoto Daisuke, a freshman in High School was suddenly exposed to someone vanishing in front of him. Turns out he was admitted to a Special Class full of Isekai Heroes that were regularly summoned to Otherworlds since the start of their Middle School. He was told that he was to become their Support to prevent each of the Heroes' fate of dying in the world they were summoned into. Though mediocre, he realized that his ability has a great potential but it needs a lot of hard work on his part.

Unconvinced of being just the Support Character, he vowed to excavate his mediocre ability, all the while supporting the Heroes using it.

And maybe more.

Wen TianHe originally thought he was a man who’s going to be a domineering chairman. But in the end, he became the man alongside the domineering chairman.

The blade of a sword must be sad for its lack in friendship. Because no matter whom it wants to give a hug, the other would be divided into two.

Utsuro no Hako to Zero no Maria, or The Empty Box and The Zeroth Maria, tells the sinister story of Kazuki Hoshino, who is almost madly attached to his everyday life, and his antagonist Aya Otonashi, who suddenly transfers into his class—for the 13,118th time. She majestically announces to “break” him, without paying heed to anyone else around them.

The journey of a generation’s male empress started because of four words.

“Send a dowry escort.”

During the 19th year of Yuanqing, Qi Yunruo boarded a carriage and entered through a corner door of the second prince’s estate. Then, across the watery corridor, he gazed at the prince from afar.

Notes:

For aristocratic women in imperial China to marry into a family part of the upper nobility, they must be of the legitimate line and must also have an escort/dowry maid that married into that family. That escort would be a “ying” (媵) and could be considered a concubine.
