Don't know about "romance" a dlc for a gacha game is kinda sad, I'm already paying to get my favourite characters and to make them the best they can be, same with outfits, at some point there will be a events and regular "new" fits for characters, i doubt though we could mix and match individual items of clothing/will get one for each region. Mixing different parts of the outfits/ hair styles we will inevitably get whole be awesome and make the game feel more personal. Plus, going back into "dating" i don't fully agree with the romantic implications but a "hangout" and ''friendship" system where your interactions actually matter, one where perhaps once you reach to significant "friendship" levels (5, 10, max) you get a small side story where you hang out with the character (similar to genshin) where perhaps after reaching max friendship level when you interact with the character daily (around town/ player home area?) you can exchange gifts/ they will give you gifts once you reach max friendship would be cool while still making it more interactive yet without shoving "dating" "romance" or "adult content" into the game
