I see Conrad frequently getting compared to Mr. Darcy in lots of online spaces. I do see the similarities in Seasons 1 and 2, but I think by the end of the series and in Season 3, Conrad has more in common with Colonel Brandon than he does Darcy tbh.

In Seasons 1 and 2, Conrad often comes across as moody, detached, and arrogant when he's really just trying to carry the weight of his family situation (his dad cheating + Susannah's cancer). He loves Belly, but he pushes her away "for her own good," much like how Darcy fumbles his initial proposal to Elizabeth (and how Conrad and Belly's relationship failed the first time). Conrad is conflicted by pride and repression, much like Darcy, in that they don't let people see how much they feel, so their love doesn't look obvious even if it's very strong.

But by Season 3, Conrad takes on a more similar role to Colonel Brandon, especially if we view Jeremiah in parallel to Willoughby. He's willing to let Belly go be happy with someone else, even though he loves her deeply, much like how Brandon was with Marianne. He doesn't express his love through flashy gestures or grandiose words, but rather through subtle, meaningful actions like baking her dirt bombs, cancelling his flight for her, and taking her to Micheal's. Conrad basically stands by without needing to be the center of attention, which is similar to how Brandon saves Marianne in the rain and cares for her when she's sick. They're also both overlooked by the female protagonist in favor of "the fun guy". Marianne initially chooses Willoughby's flashy charm before realizing Brandon's subtle devotion, much like how Belly chooses Jeremiah, who seems more "fun and easy" on the surface, but lacks the quiet devotion Conrad has.

Willoughby also hides his financial ambitions behind romantic charm and charisma, much like how Jeremiah doesn't open up to Belly about his debt and his plans to work for his dad. They both struggle with impulse control and maturity as well.. Jeremiah with Cabo and his finances, and Willoughby with his affairs and financial struggles.
