Looking for a manga

It’s Shoujo, setting in high school. Fl is not drawn ugly by default but she constantly makes scary and ugly expressions. And shes really strong. Her best friend is really cute with long hair like a doll but loves teasing the fl in love, gives stupid advices and take photographs of her scary expressions. Ml is the school prince.

• one chapter I clearly remember is how the ml remarked how he felt hurt because he had to reject girls who confessed so she went around and started scaring those girls with her scary face so they would run away instead and the ml wouldnt have to
reject them
• her cooking is lethal. She gives stomachache to those who ate her food. Ml ate and got a stomach ache and she princess style carried him and his monologue was so cool with stars in his eye.

Thanks!
