Oh wow🌌 it's really all the best aspects of the prior series, slightly more realistic, and a confession in 1 chapter instead of the second to last.  Including astronomy!  And probable autism.
I'm really excited and a bit curious why this second attempt at astronomy lesbians exists.  Sure Osanajimi felt like time-looped fluff with wasted potential, and I want this... but how often do authors reshuffle their most recent work for the next?  I hope the cast and other elements give it some distinct flare since the first chapter was focused in scope.  Ayumu needs friends and club mates to start.
