Lin Shen is a person who hides his emotions very deeply. Thousands of words are surging in his heart, but when he comes to his mouth, they always turn into silence that hesitant to speak, or insincere alienation. He is used to wrapping himself in a shell of restraint, fearing that showing concern will be regarded as pretentious, and even more afraid that if he takes the initiative to approach, he will be pushed away. Su Wan, on the other hand, was like a pool of eternally warm spring water, delicate yet resilient. She keenly captured all Lin Shen's unspoken emotions, and guided him little by little with tolerance and gentleness. In this long journey of "stretching", there are pauses that hesitate to speak, there are withdrawals after temptation, and there are countless moments of gentle acceptance. When Lin Shen finally dared to raise his head and say "I care" and "I miss you" to Su Wan, the door to his heart that had been closed for a long time was slowly opening to the wind.
