After being injured, scars will inevitably leave, and an inadvertent touch will make you feel the pain of the original wound... Aruo (Chen Ruo) is a young man born in a northern city. When he grew up, he returned to this place almost once a year because there were too many memories of his past here, including his past love, broken family, and his long-dead grandfather! Looking at the old house in front of him, Aruo understood that the red walls and black tiles he saw in front of him revealed the traces left by the years and the memories of the past. When I gently stroke the uneven wooden door of the old house with my fingertips, I feel like I am listening to it tell the story of the past. These things have left indelible traces in A Ruo's heart, and this return has plunged him into endless memories. The young man who no longer belonged to him, this old house, including the original milk tea shop, were frantically dragging him into the abyss of memory. He always felt that he had no choice about where to go in the future, whether he should forget the past and start over, or leave his memories and disappear into the crowd. Even for him, everything he encountered now was not enough to make him feel scared, because the things he encountered over the years could be said to have made his heart stronger, but it still hurt a little when he thought about it. When the cold wind blew coldly on my body, tears fell down my cheeks. It wasn't until the end that he realized that he had already buried the answer in his heart!
