She encountered her own warmth in winter, and that warmth required her to work hard for it. The warm sun will not always shine on me. Even though you are my salvation, I must work hard to catch up with you. Without a vest and various protagonist auras, she needs to survive in this messy world. "The world is so big, I have to look for my own spring." "Living is your best salvation, don't expect more. Because you will lose more."
Concept: "We are not the protagonists in life, we are the protagonists of ourselves"
