I remember the jokes and memes about "Arbert" and "Lamimi" when the first lorebook came out and blandly mentioned how Lamimi had "lust for Arbert's loins".

At that point I figure it's partly that Lamitt loved Ardbert, but also partly that she's rather thirsty.

More seriously, there's the very obvious crush-turned-love of Alka Zolka and Setoto in the SCH questlines. There's also the tragic love between Severian and W'nahja in the ALC 1-50 questline, the love-turned-rivalry between Melkoko and H'mhasi in the CUL 50-60 questline, the proving-my-love between Raulf and Anzu in the CUL 60-70 questline, and Sekka's one-sided declaration (to her father's consternation) of love to Brithael in the BSM 60-70 questline.

Come to think of it, there's a lot of romance in the crafting questlines.
