Sasuke gets an unexpected heat, and his oldest rival and once best friend Naruto is there for him.
I am more of a top Sasuke fan. But NaruSasu works for me, too. And fanfictions like these are among those that I really go back to over and over again just because of how wholesome and fluffy they make me feel.
Apart perhaps from the Mpreg aspect, this fanfic makes for a great guideline in how to write an omegaverse Naruto Fanfiction. The more I reread this fanfic the more insight I get into the omegaverse dynamics and how wholesome relationships should be written.
Definitely worth rereading over and over again.
