I think I'm going to find this one extremely frustrating. I'm going to eagerly read each chapter hoping this is the one where this pseudo-couple turns serious. Then being totally totally bummed when it's not.
I wish they put series like these under another tag other than yuri, so yuri purest like me don't end up banging our heads against the wall, in frustration, every time a new chapter gets posted.
I definitely understand the frustration so I do think at that point it'd probably be best to sit this one out til you get solid confirmation that the story will be romantic. Save yourself the heartache lol. That said, the yearning is definitely going to be the best part of this manga. That delicious, "what if," feeling. I have a sneaking suspicion that this is going to take the trajectory of "She loves to cook, she loves to eat".
