A pair of inexplicable rivals are assigned to the same class: the boy who seems to be cheerful and optimistic and is the second in grade has a repressed family life, countless negative emotions, and unknown hobbies (sentiments); he looks cold, but is actually cold.
Understanding each other, comforting each other, understanding each other, and redeeming each other. Perhaps it was similar experiences that brought the two together, perhaps it was the tacit understanding of being against each other for many years that made the two people unspoken about each other's feelings, or perhaps it was their childhood experiences that left an indelible mark on each other when they grew up and became the most important position in each other's hearts.
Purpose: Mutual redemption
