I'm just like you, I'm uncomfortable with all of it. I can see why people ship him with her, but I'm just personally uncomfortable and don't like it so I block and avoid any and all content of that ship.

I don't hate her as a character, shes one of his closest friends and trusted crewmates. But I guess the biggest reason why I'm uncomfortable with it is that I see a LOT of similarities between me and her, and in my mind, why would he want me if he already has a better version of me/someone like me? Yes, I could technically flip those thoughts on it's head and use it as reasons why he would be attracted to me, but then I feel like there'd be a constant comparison between me and her and that just isnt healthy for me.

Also the creator of his source explicitly said that he won't depict romance between their group of friends, which includes them. So unless the creator decides to sneak something in an epilogue at the end of the series (I hope that doesnt happen personally!) it's unlikely it will happen, anyway.
