No lol, it's just a kiss with Shadowheart. If you watch the community update on companions and romance you'll see that the game will not *fade to black* xD. I thought her romance scene was the sweetest of any of them, tbh, and I think she has the most potential as a romance option so far. (Which is a shame for me because I like Astarion but I KNOW that one isn't going to end well.)

But I've noticed a lot of whiplash with the character interaction, even outside romance. In a conversation they'll be acting friendly with you and then you open up their default dialogue and they treat you like a pest. I'd like some more consistency.
