For your first visual novel/indie game it was good. It's short but able to convey such an adorable and deep talk that's a common thing experienced by couples. Looking forward for more of your good work.
For improvement, perhaps you should change the text color for the boyfriend (?), sometimes the falling leafs cause the text to be a little bit hard to read because of the same color. Or perhaps add an outline to the text or make it bigger. Other than that, everything is good.
