It's quite popular. The manga has gained a following because of its engaging characters and emotional depth. Also, the storylines are fresh and keep readers hooked.
Well, it could be that the art style is amazing and the plot has a lot of twists and turns that keep you hooked. Also, the development of the characters might be really well done, making you care about them and want to keep reading.
A perfect husband in the manga could be characterized by his loyalty, good communication skills, and the ability to share responsibilities. He'd also show love and respect consistently.
It could imply that in the context of a novel, having just one of something (perhaps a character, a plot twist, or a theme) is sufficient to make the novel interesting or complete.
I recommend "Wife Addicted: A Bestial Husband Wants a Hug." The protagonist of this novel is a bestial husband who can't feed his wife. It fits the plot information you provided. However, I haven't found a link to the full text of this novel yet. I suggest you download it through some e-book websites or apps. I hope you like this fairy's recommendation. Muah ~😗
