Romancing could be similar to Wondrous Tales in regards of style where the NPC you choose to romance can be talked to weekly to receive a romance quest that would require random tasks.ect

Choosing Aymeric as a love interest could debatable affect the story but Aymeric seems fond of you anyway so it wouldn't really affect anything as romancing is something of a private event.

The romance system could also work like Beast Tribes with ranking. Hitting certain ranks in the romance could result in random rewards after dates have ended.

Thanks for reading if anyone manages to get through this xD Let me know what you guys think as this idea is supposed to be something that is do-able/practical and could be fun for players ^^
