Most of us have probably watched or read a series like Eromanga Sensei or Ore no Imouto. Anime and manga more often than not, sprinkle romantic feelings in brother-sister relationships. Not to criticize this, as some people do enjoy these types of shows. However, as a person who has a little sister, I do find it quite weird and very unattached from the real world.
However, this series is different. It's one of the closest representations of a sibling relationship I've seen in quite a while. Siblings don't have weird romantic encounters, they fight. A lot. They argue over everything, cause disputes around the household,
and make sure there is no peace anywhere when they are with each other. But when time comes when it really matters, siblings are one of the best people to look towards for help.
What makes this series great is that it accurately represents what most siblings are like. Of course, it often exaggerates to add comedic effect, but I can confidently say that my relationship with my sister is quite similar to this series.
If you just want a quick read, or maybe a taste of what a sibling's relationship looks like, give this series a try. It's a fairly short read, and you probably won't regret it.
