The story begins in Food Wars, when Alice took him home.

Having transmigrated into the world of "Cooking Master Boy," Bai Yuan, trapped in the world of dark cuisine, has, through decades of relentless effort, defeated all five members of the Five Tiger Stars with his astonishing talent, becoming the new strongest in the world of dark cuisine.
Just as he reached the summit, ready to enjoy the power of the organization and marry several beautiful wives and live a carefree life, he was transported to another world. When he woke up, he found himself in Food Wars!
The good news is that the female characters here are more in line with his aesthetic; the bad news is that he is currently penniless, starving, and it's snowing in the distance, making him feel like he's about to freeze to death on the street.
Fortunately, Alice Nakiri, who happened to be passing by, took him home and kindly brought him food. However, because of her limited cooking skills, he subconsciously showed his disdain and immediately became angry.
Feeling he had gone too far, Bai Yuan thought about it and decided to show off his skills by creating a top-notch glowing dish. Thus, he naturally became Alice Nakiri's personal cooking teacher.
However... the private cooking teacher we were promised was definitely not some kind of love coach!
Looking at Alice Nakiri, Erina Nakiri, Hisako Shinto, and Ikumi Mito who were closing in step by step, Shirayuki's lips twitched slightly. Something seemed off about how the plot was going!
