The following are some interpretations of this lyric:
This lyric depicts a deep attachment and persistent emotion. In poetry, direction is often not just a direction, it often represents a symbol. For example, "going north" in China culture often represents a long journey away from home, challenging the cold and hardships, and symbolizing a kind of determination and tenacity. So "you turn to the north" may mean that you have chosen a difficult road and you have decided to meet the challenge.
"The side face is still beautiful", and the "side face" here is a perspective and a symbol. It may represent a one-sided and incomplete view, that is to say, although I can only see your profile, you still look beautiful to me. The "beauty" here refers not only to the beauty of appearance, but also to the beauty of heart, your tenacity, your determination and your courage. So the meaning of this sentence may be that although you only show a part of yourself, despite the challenges and difficulties you face, you are still beautiful in my eyes, and your inner beauty shines more brightly.
Generally speaking, this lyric expresses deep admiration and persistent pursuit for someone. It does not clearly depict specific scenes and characters, but expresses emotions through symbols and metaphors, which makes this lyric poem have profound connotation and poetry.
