Well, there seems to be a misunderstanding. I never intended to romance all girls at the same time. From the start, I've been clear on that. This isn't a harem game.
I love Chasing Sunsets. If you want to see the full Chasing Sunset x Summer Scent cross over, you will have to play a path including romancing Eve. That will open some scenes you might like!
Working that route now. I like when authors do cross overs, it leads me to other great VNs. As for yours, I gotta say the Cassie path is ... interesting. Looking forward to finding out what Kelly is into.
