I'm impressed, I started reading it because I thought it would just be a silly story focusing more on sex, just to pass the time and laugh a little, but it's one of the best lovers' rivals I've ever read. The author knows how to build a real rivalry, this is the relationship you imagine when you think of rivals and it still manages to be a healthy relationship. The context of firefighters is very interesting. And they are two big, strong men, both very good at what they do, without stereotypes and without that "hehe he's as cute as a girl" thing. There isn't alot of drama in terms of accepting feelings, which I love, but in other things I found it interesting to follow. Mainly because everything revolves around their rivalry and how it makes them better, instead of ending everything. I loved it, it's very cute too, there aren't many declarations of love, but I identified with Yajima in this. I could read 10 more chapters just about them being lovers, because I loved their interactions and dynamics.
As it's short, it's not something that will mark my life, that I'll never forget, because it doesn't give much time to get so attached to the story and characters, but it leaves that feeling that it would be possible with more.
