Throughout its creation, I kept recalling the time I came to London, and experienced depression for the first time. That period felt like a literary scene where "the sky is always gray." Depression and sadness arrived without reason, as if they were the key to opening the door to adulthood, more like a cloud gathering overhead. Looking back at my panicked self after gradually learning to coexist with these emotions, I realized that the cloud was merely a void I had created, obscuring all the light. But these are what shaped who I am today. I coiled up a fragment of my past self to commemorate.
