Hi, there's no certain release date yet. Likely April or May.
I post weekly reports on my Patreon and SubscribeStar where I report on my progress, so keep an eye out for those. They're public, so you don't need to be a subscriber to see them. (I might actually start posting them here too in the future.)
Choosing Ashe's partners is definitely something you'll see more of as the story progresses. I aim to leave the choice who she'll end up in bed with to the player as much as possible. For story reasons there are certain key points (like the scene you mentioned) where that's not always the case.
