I think the yuri tag should probably be removed unfortunately. After reading up until the end of volume 1 from the Spanish translation it seems like there will not be any romantic development after all. It's a shame but I suppose this is just another food/friendship manga.
What could possibly make you say that?
The romantic relationship between Momo and Yuzu has been progressing steadily since the beginning. If you have read the Spanish translation, you should know that Momo has already admitted to Yuzu that her feelings for her are more than friendly. And that she asked Yuzu for a little more time before deciding if she will go out with her or not. (Actually, if you listen to the other characters, everyone and their uncle had already realized that Momo liked Yuzu that way... it was only Momo who was in denial.) And recently there's another girl x girl couple that seems to be forming. Of course this is a yuri story!
