The Misfit of Demon King Academy (WN) - Chapter 28.1

Before her rebirth, she was abandoned by her parents, then murdered by her seemingly pure but vile younger sister. After her rebirth, she kicked all her scum boyfriends to the curb and began a campaign of abuse against the superficially perfect. Rumors were rife on the internet that Qin Sheng was a kept woman? A bunch of computer nerds, "Let's hack the keyboard warriors' computers." The first director, "Boss, have you written the script yet?" The medical expert, "Sheng Sheng, our research institute will give you 100 million. When will you be able to join our team?" A famous painter, "Sister Sheng, take me along when you hold your art exhibition." The CEO of a billion-dollar company, "Boss, when are you going to publicly disclose your identity?" Finally, a big boss pulled Qin Sheng into his arms. "Sheng Sheng, I've transferred all the assets under my name to you." Netizens, "?? This world has suddenly become crazy?" She was a business genius, a computer genius, a legendary screenwriter, a legendary painter, and a legendary medical expert. It remained to be seen how she would create flourishing prosperity. (The male protagonist has a propensity for recognizing bitches, but is infinitely sweet and doting to the female protagonist!)

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.

She, a genius abandoned by her clan. He, a proud, pampered, two-faced imperial crown prince, a developing supreme ruler of the world. She, tricking him, disguised as a pig to eat a tiger, suppressing him, provoking him. Every time, after playing with him and stirring him up, she’d escape.

No man could put up with this! He could only hunt her, pamper and indulge her, lure her into falling in love with him, who would have thought, the one to first fall in love would turn out to be him———-

A young man who stood above the world, a young lady who dominated the landscape, evenly matched opponents, evenly matched romantic game of chase and tag.
