Story: 7/10
The story is simple and that's all it needs to be. Girl has niche hobby, Guy has niche hobby, they find a connection that no one else can give and romance ensues. My one complaint with it is I feel it focuses a bit too much on the cosplay lifestyle rather than the romcom/slice of life for my liking but is a relatively minor as things go for me.
Characters: 7/10
I don't have many complaints with the characters, I enjoy Marin and Gojou and the side characters are fine, however the longer the story goes on I am loosing interest in them and wish they focused a bit more on the two main characters
Art: 9/10
No complaints here, good artwork with nothing negative that stands out, however nothing out of this world for me
Overall 8/10
I really like this manga and has had me hooked for 90% of it's chapters, my only complaint is at the time of writing with 82 Chapters, I feel like its starting to drag on a bit however I still have my hopes for it and still highly recommend it to anyone if they even slightly enjoy slice of life or romance manga.
