I've played four of the routes so far and I've enjoyed them but all of them were solidly friendship at the end and I was hoping for a romance! I'll see how the next two routes go.
It's definitely more of a friendship-focused story than an explicitly romantic one: maybe because the characters are all from other VNs of mine, so they have canonical partners in the stories they're actually from haha ;;
I guess part of me thought it would feel odd to explicitly hook them up with the main character. I'm glad you found the story enjoyable despite that, though!
