This is actually an absolute banger of a story! No non-con, a lot of chemistry, they are really respectful of each other's needs, their relationship building is magnificent, and I loved when her sister asked him "could it be that you're afraid they'll die?". The idea or a "narcissist" being abandoned and wanting to be loved and someone who is afraid to love is so so so good as a formula if done right, and I think this story manages to do it amazingly! Love the author. Can't wait for more
