Wow this is quite interesting. A different take on childhood friends to lovers. There was no hurdles, the two naturally just levitated in each other's life and when feelings were brought, they just naturally started loving each other. It was like a smooth transition, as if it's the natural course of their relationship.
I love the take on how they are not only friends, brother but also lovers. That they are all of those. That they don't want to be a special one to them but just a person with them.
Waiting for ch.6
