Does it have spoilers or is it not that relevant?
It doesn’t necessarily have spoilers, it’s just background into this story since it’s a sequel. GED goes more into how we got here in this story and also explains some of the things in it too. Overall I do 100% recommend reading GED, it’s hilarious as hell and just a good read in general. Of course you don’t necessarily need to read it to understand this one.
It’s yaoi. The uke and seme were childhood friends but they got separated because of uke’s mom was so strict. They reunited in high school. Uke is living with his grandma and he has a cat. His grandma has a small diner I think? Seme has a pet dog, looks like Shiba Inu?
This is all I can remember
