Ah, high school. Is there any better place to start fresh after a horrible middle school relationship? Nope! Not unless your ex ends up at the same school as you and is now your stepsibling. What was supposed to be a sanctuary of peace where I could avoid ever seeing her again has become a living nightmare! Everywhere I look, I see her—in my house, in my school, in my class. There's no escape! She even claims that she's the older sibling. Like hell she is! But I won't lose to her. After all, I'm the older brother in this new family situation. That's right, we're family now. No matter how much we may have thought we loved each other before, we saw one another's true colors and realized we weren't meant for each other. That's why even though we may keep up a buddy-buddy sibling act for the sake of our parents, things will never go back to the way they used to be.

Preliminary (17/? eps)
One of the best LNs I've read. Remember THIS IS NEITHER INCEST NOR NTR, I've seen some rascals misunderstanding the title and commenting their own BS so do not get misunderstood.

They're slightly different from osananajimi but I like their ...

Preliminary (50/? eps)
I came to read this novel after watching the first episodes of the anime, as I was curious about the initial setup and thought that the novel could be richer. I was interested because it was depicting in a slightly roundabout way how a couple has to reinvent its relationship after the initial passion, and how that was possibly a difficult process with a lot in introspection and painfully revisiting past errors.
And in fact, that first 4 volumes do that job pretty well and allow us to dig deeper and deeper within the complicated relationship of Yume and Mizuto. Apart from some scenes that ...

Preliminary (100/? eps)
Like many people, I was intrigued by the premise having seen an ad for the anime on Youtube, and wound up reading the manga followed by all eight (8) volumes of the Light Novel (thanks Hellping) because I grew invested in the story.

If I was to sum up the pith of the narrative, it is about two people finding their place with each other as sibilings / potential lovers, despite carrying the baggage of having broken up with each other some two weeks before the main narrative begins. The key questions are: what does it mean to be a lover, where does the line ...
