Okay, I read a post in the earlier comment section about what's gonna happen, and I came to the conclusion that this story is of "that" kind, where author has not much idea of what to do so they go in the "drama" route.
Our guy is really not like that, to ignore his wife for a month, barely even communicating with her, though her reaction of ignoring it suits her, but again, cannot understand why our guy wouldn't talk with her or didn't get what he is doing wrong. He's in a business handling clients but doesn't see his own mistake.
Also, the drama can get over in 3 chapters, like they passed a month in last 3 chapters, but author has nothing else so they will extend this arc to 7-8 more chapters.
Worse part is that our girl opens up at the end, so our guy is still dumb, and our girl goes against her personality till now because even the author thought that the drama part is dragging... Or ig the author doesn't like the guy, he acts like he's 12 years old, irritating.
