Yep. It's so... earnestly yet badly written. (To clarify, that's regarding the fanfic, not the show. Because that needs clarifying.) The main character runs around shirtless rather a lot and this is a substantial portion of the show's charm. Damn, he is a fine-looking thing.
Do note that the wrongness is largely in execution, not in concept. I am not in love with mpreg fic but it's not a dealbreaker. The actual problem here is that subordinate clause mess and the utterly clunky phrasing it contains.
