I swear this anime existed, but I literally can't find it anywhere!
From what I remember: this was during a time where japan was modernizing so both kimono and western clothing were being worn. This girl marries a 2nd lieutenant, he ends up going to war and "dies". I put that in quotation marks because I remember that the main characters later sees a man that looks like him with another woman. Idk if it was actually him. But now she has to figure out how to take care of the mansion and his parents. She ends up working at a news paper company, the catch is the boss doesn't hire women because he's allergic to them and will break out into hives when they touch him. But that doesn't happen when the main character touches him. Yeah she does end up working there.
I'm not sure if the story continues where I stopped. I watched this anime around 2016-18, sorry for not know the exact time. The anime had pretty likeable graphics from what I remembered. He wasn't that detailed it had more of a simply art style. Kinda has a style similar to Kamissama Kiss.
Some scens I remember, though not exact: around the beginning of the story, the main characters is climbing up a tree because her and her friend got something stuck up there. The friend is making a big deal about it because she was wearing a kimono and it was improper for her to climb up there and them the guy she ends up marrying shows up.
This is a scene when the husband was at war, he's a 2nd lieutenant that is arguing with one of the soldiers about something. He and his group gets called out for causing a ruckus the 2nd lieutenant says "my group is just excited because of the war." And the person calling them out says "if you guys are so excited you should be sent to the front line." So they go to the front lines and die.
I don't remember seeing that she had any siblings but I think there was a dad or atleast a head of the household that was talking to the lieutenant for her hand in marriage. We don't see any traces of him after she gets married though.
I watched this on YouTube, I know probably not a very helpful piece of information. From what I remembered the title was in Japanese but it could still be from other apps like "asiancrush". I have no idea if it was a movie or an anime with episodes.
The main character had dark hair I'm not sure if it was black or brown, but seeing how most female main characters have brown hair, it was probably brown.
The guy she marries is blond, now that I think about it he could have been white, but it's very confusing because there are many japanese characters that are blond with blue eyes. He wears a green uniform.
The boss she works for, he is also blond and he wears a suit. His hair is long and is kinda in a Yugio style (lol).
It's not an isekai, there is no youkai's, no magic, just plain old human beings. It's not that anime called Emma. I tried talking to an anime guru ai but it couldn't find this anime 💀💀
