As someone who suffers from anxiety, a few moments in this short VN struck quite close to home when it comes to relationships I've been in. Always trying to say the right thing, to learn from your mistakes, to be super aware of what you've said, what you've done, and how your partner responds, positively and negatively, and ultimately be better each time one of those tense moments occurs. Oh yeah, I've felt that many times over, so you captured that feeling of struggling with anxiety within a relationship.
My only criticism would be something that was also said below: a bit too many "..."s in the story. I'm a HUGE fan of using ellipses in my own writing, and it works really well to sell the awkwardness of certain moments in this game, but having to click through each of the dot, dot, dots is a bit frustrating. I wonder if you could set those particular lines to be unskippable and only show one for "You" and one for Nicole? I think that would allow for the awkward pause while avoiding the frustration of clicking through so many dot, dot, dots in a row. Just an idea :)
I'm looking forward to seeing what you come up with next!
