Looking for recs

Looking for recommendations of a good story with a male LI who I am likely to find an interesting character. Just to give an idea of the kind of characters I find interesting/compelling story-wise in other media, here's a list of some examples:

Boromir (LoTR), Jaime Lannister (GoT), Endeavor (MHA), Gortash and Raphael (BG3), Snape (Harry Potter), Angel (Buffy), Crowley (Supernatural), Flynn Rider (Tangled), Dalinar (Stormlight Archive), Tony Stark (comic book version only).

If there's any LI who has similar vibes to any of these, please recommend me that story/LI!

I have already read: TTS, Haze, KFS, SOTCN, HS1, HS2, ABH, Averris, The Missing, WLBE.
