All shoved into a single volume, it’s very rushed and doesn’t give you much time to get attached to the characters, but it is a cute short story. It’s one thing to stick to a plot and cut out any filler, but it’s another thing to jump around adding more plotlines and rushing through things like “by the way, this also happened” and “sidenote: these characters are like this over here” and rush it in a few panels and then finish it all up with a deus ex machina, the end. :/
I’m not really a huge fan of ‘psuedo-incest’ myself in the first place, and am of the opinion that it doesn’t matter if you’re not blood related, if you’re raised together- it’s kind of messed up to get together romantically. Regardless, just judging the story by its other qualities, it still falls quite a bit short.
