Hei, Wilfred is my baby ah. I think, the reason he is not ambitious (in love/power) anymore might due to the whole Rozemain being too OP as his fiance and sister, the powerful factions and people didnt really support him with how he was being raised by Veronica and he was dethroned as the heir as punishment before. It crushed all his self confidence and self esteemed to be a leader again. Aaaaahhhhh . . .
