My wife and I had been friends with this other couple for years. It was only after a while that the wives had started talking, and both found out that we the husbands had been involved in the Hina-Rui wars in the 2010s. Up until then, we had never said a word about it, never mentioned it. It was so divisive, it was like having an alcoholic father, "Shhh, we don't talk about that!" And the manga fandom had been like that with Domestic Girlfriend, and it's been only very recently that Gen X and the Millennials are starting to say, "What happened? What happened?"

Kei Sasuga's Domestic Girlfrend manga began in obscurity. It ended, six years later, in failure, witnessed by the entire manga world. It was begun in good faith by a decent artist out of fateful lack of planning, artistic over-confidence, and editorial miscalculation. And it was prolonged because it seemed easier to muddle through than to admit that it had been caused by tragic decisions, made under a series of editors, belonging to multiple editorial philosophies.
Domestic Girlfriend seemed to call everything into question: The value of sacrifice and love; the qualities of cruelty and mercy; the candor of the artists' intentions, and what it means to be a manga fan. And those who read through it have never been able to erase its memory, have never stopped arguing about what really happened, and who was to blame, why everything went so badly wrong - and whether it was all worth it.
"In waifu wars, there is no victory. There is only destruction. Some may celebrate the triumph or defeat of this waifu or another, but it is all hollow. Only those who never fought like to talk about who won or lost."
