It's a decent ending, another chapter or two could definitely help it have a more satisfying ending. But it is what it is. Still a really interesting read with a really good start and concept. Also unrelated but while reading suddenly I remember onk, and you know what I kinda wish onk ending are more similar with this lol.
This had a pretty interesting theme. The psychology behind their actions and feelings were well explored.
I know I signed up for this but the entire time I was like... but they are brothers...
It feels blasphemous to say this about a BL, but I don't really want them to have a romantic relationship. Haruto doesn't really seem to be attracted to Asahi at this time. That needs a lot more development before I could root for them as a couple.
The thing that I take from this is how much Asahi in particular goes on about family. To me it seems as if the Mangaka is attempting to say what an important thing it is and that you shouldn't abandon it. However the way it's written is that it comes across as something that consumes you and you need to escape from it. Haruto nearly managed to do that but in the end his choices were frying pan or fire
