Comments of chapter undefined of Rebirth: Divine Doctor, Sweet Wife

The sister is a glutton and the brother is friends with ML... Do I smell a potential best friend for MC. Even though she had a crush on ML, she’s at least decent and will probably not do anything bad and wil hopefully get over her crush. In fact, wouldn’t it be funny if she start worshiping MC (because of food) to the point that ML become jealpus?
