So, the fact that Ast is worried that he's so bad that he decided to seduce you to help him, but realized that you're awesome and fell in love.... well, it's like a teen movie from the '20s where the prince of the school falls in love with the nerd for fun, but then for real. (Ha-ha, pardon the comparison).
Hahaha. It felt like that for me, really. Everyone has their own taste and it's great, that there are different paths to choose from. I am not into "romantic" romance scenes, especially not where the couple is expressing their love like this confession scene. I prefer enemies to lovers or dark romance stories with roleplaying D/s or kink, so I really liked Astarion's act 1 and act 3 (AA) romance scenes, all general scenes, and dislike (or better say: not so my taste) act 2 confession, though the hug and neils voice acting is great. I understand when people love this scene. I go with AA and I am happy with it.
So, still hope, it was just a fanfiction idea, which went wrong, in patch 6 and they will change Tav's facial expressions. Because trying to teach or educate grown up people or subs, who like (!) and want to roleplay dark romances, kink or BDSM in a fictional fantasy world , is not only gross, it's a nonsensical, ridiculous, very comical thing and a disservice. What would come next? Trying to teach homosexual people or those who romance the same sex to get straight? I hope not!!
