Drowning happens in silence. When water has flowed into the body, you can no longer speak at the moment of consciousness. Mu and An, two people in love, changed their relationship because of a butterfly. The moment the relationship changes, so silently, the former doting has now become suffocating, but by the time you realize it, it is already too late. Love has penetrated deeply into life and cannot be let go. When love has become a part of my body, I can only leave you if I abandon myself.
