This manga is about Mayuko, a girl whose having problems with homework and gets help from her classmate Haru, who loves astronomy.
The artstyle - I really liked the artstyle, even though it's very simple it shows detail, and it has a soft feeling to it
Story - in the first volume of the manga we see Mayuko and Haru get to know eachother. Their enteractions are very cute and it feels natural and not rushed. The story has a connection with stars, in particular the star sirius hince the name. The title is so fitting but am not going to put spoilers but it makes so much since and the reason for it is really cute
Characters - The characters in this manga have depth and are consistent. I found Haru and interesting character along with Mayuko (also the rest of the cast) The way the characters talk and their internal monologue's feel realistic and natural
Final Thoughts - I wholeheartedly enjoyed reading this manga, and getting to know the characters wants, backstorys and so on. I highly reccomend this manga since it's a very short read (like 1-2 hours) it's a sweet read. I hope this review makes someone give this manga a try since, by the time am writing there hasn't been any reviews for it
