I mean it’s a fanfic and the world could be an AU so if you really want the ages to be closer and Romanda to be his only wife no one should complain. Plus you’re story so go ham on the details you want instead of following all pre established facts. Like say T’Challa is 18 and the MC is 13 so Shuri could literally be a year older than the mc or be smack dab in the middle are wise.
