A young man brings his girlfriend home for dinner, but his mother’s reaction to the girlfriend’s “broken palm line” startles her. Sensing her anxiety, the mother shares her own experience, explaining that the line isn’t a curse but a sign of strength—and that what truly matters is whether a woman meets a partner strong enough to stand beside her.

Throughout the meal, the girlfriend witnesses the parents’ easy banter and their forty years of facing life’s storms together. On the way home, the couple talk openly; the man says that saying “I know” carries more weight than “I love you,” because it means seeing future challenges and still choosing to walk together. For the first time in her life, the girlfriend learns not to hide her hands, but to show them with pride.

一位男生带女友回家吃饭，母亲看到女友掌纹中的“断掌”后神情复杂，引发女友的不安。母亲随后以自身经历化解迷思，告诉她“断掌”并非不祥，而是象征坚强，关键是遇到能撑得住、配得上的伴侣。餐桌上父母的互动，也让女友看见男生家庭里那份四十年风雨同担的深情。回家的路上，两人坦承彼此的心意——比“我爱你”更有力量的，是那句“我知道”，因为那代表看见未来的艰辛却仍愿意携手前行。最终，女友第一次学会以骄傲而不是恐惧，摊开自己的双手。
