I really found Melissa to be adorable and likeable. All the chibi images made me smile a lot too. Even though I know it isn't considered one of the main advertised romance options I really liked the Joan romance a lot. I found it incredibly cute especially considering how well they interacted with the language barrier.
Definitely going to be taking a look at the other games here. I was thinking about Heileen next. I'd really like to try Nicole as well although I figure I'll wait until the female romances are out (seems like that could be a while but I *really* hope it does come out eventually

Thank you to the creators though! It was a fun experience and I hope the other games are just as enjoyable
