kou talking about when his mom had really bad morning sickness and could only eat tomatoes, so that's what she ate, and ririmu asked him if that meant he grew up with tomatoes...and he said yea grew up as a baby inside her stomach with just the nutrients provided from tomatoes, but now she's disgusted at tomatoes whenever she sees them, and he also hated them as a kid but now loves them a lot, thats good ririmu said

ririmu lived eating lots of tomatoes, and at school lunch too, she said that since kids hate tomatoes, she would gather tomatoes from all the other kids, and her plate would be filled with tomatoes

oh and kids love milk too
