Qi Siyun seems to have never liked this noisy world, so she thinks it's nice not to be able to hear. She can quietly do the things she likes and live her own life, until she meets Gu Yan, and that ray of sunshine finally reaches her heart.
In Gu Yan's eyes, the world is colorful. Even if sunlight can't reach every corner, warmth is never absent. So before meeting Qi Siyun, he never imagined there could really be corners the sunshine couldn't reach. That's why he wants to throw caution to the wind and go to her side.
If we'd met sooner, you might have fallen in love with this world sooner. Luckily, everything has worked out for the best. Before darkness falls, I can finally say: Qi Siyun, how fortunate I am to have met you.
Theme: How fortunate I am to have met you. I would give everything just to see you again.
