The song "Habits (Stay High)" by JISOO tells the story of someone who is struggling to move on from a past relationship. The lyrics describe how the protagonist feels lost and alone without their lover, and how they resort to substance abuse to cope with the pain and memories of their past. The repeated phrase "High all the time" is a reference to the use of drugs or alcohol as a way to numb the pain and stay distracted from the reality of the situation.
The winter imagery of the lyrics is also a metaphor for the emotional coldness and isolation that the protagonist is experiencing after their partner has left them. The line "You're gone and I gotta stay" reflects the feeling of helplessness and despair that comes with the end of a relationship, while the repetition of the chorus emphasizes the addictive nature of the habits that the protagonist has developed in order to cope with their loss.
Overall, the song portrays a sense of yearning for the past and an inability to let go of what once was, leading the protagonist to seek solace in harmful coping mechanisms.
