Walden is your moon and you're his sun. Well, That's also how your relationship works. You proposed to Wally, Your boyfriend only for him to look away in disappointment.

The sun proposed to their lovely moon. But their handsome moon replied, "I don't know, don't know so leave me alone..."

In those emotionless eyes you can hint sadness as if he was holding something back. Maybe he wasn't ready or something hurt him back then to have trust issues. Who knows... But you'll always wait.
