SPOILER WARNING!!!!!
Senia gets support from her brother (Lancelot) to get the kitchen key. After that, Senia started cooking and almost every day she was always in the kitchen. Not happy with the changes that have happened to Senia, Floretta (Candidate for Senia's stepmother) plans to get rid of Senia because she considers Senia as an obstacle to her goal in the house. Floretta plans to destroy Senia by humiliating her at a party held at her house, because at that time Senia will cook for her grandfather. Floretta, who doesn't know about Senia's ability to cook, calls her nephew who is a cooking academy student as a chef. in fact, it was the chef who was paid by Floretta to cook. However, the plan failed because it turned out that Senia's food was preferred by her grandfather (which happened at the beginning of chapter 1). In return for Senia's cooking, her grandfather will grant Senia one wish. Senia then asked for justice and hoped that Floretta was expelled from the Frenchis residence for hurting her. Her grandfather then granted Senia's request and then conducted an investigation into Floretta. After all that was revealed, Floretta was kicked out of Frenchif's residence. After the incident, Senia's grandfather and his older brother (Gawain? Green hair) began to pay attention to him, which they didn't pay attention to before because Senia always avoided his family.
Sorry if it's confusing. I used google translate because I was confused to explain it in English.
Btw, for Male lead, until chapter 17 it's still unclear, but later a black haired man will appear who I suspect is the male lead.
That blonde brother is still sus. But could someone please spoil this story for me??
