Well,
@Oh_my_goddess : that was an excellent comment. I want to add to your point something from another perspective.
Slice of Life stories have a way of pulling us into a set of drawings as if they're real people, then grinding up those people into some almost unacceptable situations, then spitting them out at the audience for effect. It's tried-and-true, no doubt. Cliché, no doubt. Almost as tired as "throw a tsudere sadistic tease at a loner/soloist and watch the antics ensue" trash.
Many of us are invested in the characters and lightness of the story's romance and tenderness. So an upset of this magnitude may be considered by some of us to be over-the-top, kinda like sending a tsunami toward some small child playing in the sand at the beach. Perhaps something smaller but still complicated should have come first. Nevertheless, the is the direction our writer wanted to go. Judging by the number of views over here at Mangadex, this is a very VERRRYY popular manga. And if we come to these pages for a bit of relief from other stories that leave us high-and-dry, then I fully sympathize and empathize with those who are upset.
Perhaps it is the highest of silliness to "trust" a manga writer, that he's going to be able to take this wave of destruction and make something of it that works, a bump in the road we all look back on and are very appreciative that it's just one major hiccough in the past as all things return to "normal." And if this is our mangaka's first attempt at a story, then I'm willing to hang on.
I enjoy a good story. Story is first. And since we're stuck here in time, I'll wait patiently for the next few chapters to unfold. I'll be drumming my fingers on the desktop as I wait. But I won't be so entitled that I'd throw nasty comments at the author. I'll wait until there really is a train wreck before yelling out: "Train wreck!"
