Vol 1 is tagged as yuri in dengeki bunko, Vol 2 is not. Take that as you will, I doubt you people should have high hopes for them ending up together or anything of the like, though.
In my country a high school girl who can cook is highly praised, because we loves to eat especially homemade cooking (yup her friends (especially boys) will love to hang out in her house just to eat). Then she will rarely eating alone.
@gearoi92 shoujo-ai is actually not yuri right, it tells a 2 relationship so close people think they are dating, but they actually not romantically attracted to each other. Btw that tag is born from outside Japan (Japan themselves dont have this tag) to differentiate themselves for normal Yuri.
