In these lyrics, the protagonist is talking about how many people she can love in her teenage years and how she is always looking for something. She wants to wash away any stains and make her heart pure like white, using gentle bubbles. She mentions that her partner still can't forget someone from the past and leaves white flowers by the river as a sign. She also talks about how people hurt others with small lies and always end up regretting it, but despite that, she still wants to experience love. She mentions that she has learned to love a little in this town and asks her partner to come and see her again. She confesses that she has been foolishly in love and still has a lot of things she wants to know. She wonders how many times she can succeed in 10 tries and that she is looking for something gentle in her heart. In the end, she mentions that she loves her partner's smiling face that she sees through the viewfinder and that their secret will always be a secret. She expresses her desire to be by her partner's side just like that day, but acknowledges that they will eventually have to part ways. However, she believes that their love is a miracle and that everything they experience together, like falling in love and tasting kisses, is part of their story. So she asks her partner to come and see her again, not to disappear, because there are still so many things she wants to know. She realizes that on days when her heart feels dirty and hopeless, she can wash away those feelings by remembering that day and cleansing her heart with gentle bubbles.
