Hahaha -- I had this same situation when I went overseas to stay with my relatives who were gracious but we didn't speak each other's languages. Thankfully, we had a variety of meat dishes, and they knew I liked fast food. Thanks for the translations!!! πππ
Hope this series does a good job of pulling off the difficulty of a language barrier! When I was a kid, grandma took care of us when the parents were working -- but neither of us spoke each other's language. I remember the time she was hungry and I fed her instant ramen. Perfectly fine for a kid...
If you like delusional fujoshi side characters, stick with it. I preferred the "gangster househusband" manga for the gag setup this manga uses (of heavily suggesting one thing and doing another).
