I have a save right before the baking date with Aline, and I want to know if I need to reject her now to get her and Jade together. My current plan is to match up Aline and Jade, but I also want to be greedy and not miss out on any of the date scenes with anybody..
Right now there are only two romance scenes canceling each other entirely. If you support Jade x Enzi, you get a scene with Jade going to the Velvet Touch for advice, otherwise you can go in a date with Jade. The other descission only change wording in romance scenes.
The Jade x Aline path is planned, but not yet implemented. In Update 9 I plan to address both the alternate romance path (Aline x Jade, Enzi x Jade and Stella x Mike) and the approach to the Harem ending.
