我想我已坠入爱河

“

Look, I...
I like you too, OK?
Whatever way you meant you like me, I like you too.
It's just...
Being with you...
Makes my days better.
Makes 'em... some of the best days I can have.

” ——Susie to Noelle, Chapter 5

I guess I'm in love is the 8th track of the DELTARUNE Chapter 5 OST. It plays while Susie and Noelle watch the sunset at the lake after the Festival.
