"What Can I Do" is a song by the Swiss rock band Gotthard. The lyrics express the longing and desperation of a person who is deeply in love with someone. They constantly think about this person and see their face everywhere they go, indicating a strong emotional attachment. The protagonist feels like a pretender, as they try to hide their true feelings and continue living their life without the love they desire. They reminisce about past times spent together and openly admit that they need the other person more than they will ever know. The song conveys the protagonist's yearning for the other person's love and their despair at living without it. They question what they can do or say to make the person love them or even just make them smile. They eagerly await a sign from the person they love, begging them not to turn away. The protagonist wants to know if this is the right time and place to confess their feelings and wonders how they will feel when they finally do. The phrase "walking on fire forever, after" suggests the intensity and passion of their emotions. The lyrics also indicate the protagonist's willingness to be there for the person they love, to provide support and be their rock. They hope to fill the other person's mind with dreams and be the one to catch them when they fall. The lyrics emphasize the importance of trust and following their hearts, believing that love will follow. The song speaks to the universal experience of longing and unrequited love, capturing the desperation and hope that come with it. It portrays a person who is willing to do whatever it takes to make things right and change the other person's mind, hoping to find a way to express their love and be with them. The lyrics leave the outcome open-ended, asking the other person to tell them their true feelings and give them a chance.
