A love story part 3

Another year later, once again, the girl's girlfriend came to the girl with an invention card. She opens the card and sees that it is the boy's marriage invitation card. The girl is surprised when she sees her own name in place of the bride. When the girl wants to know something about her, she sees that the boy stands in front of her. The boy then used the word "sign language" to say to the girl, "I've spent a year's time to learn sign language. Just to let you know that I have not forgotten our promise. Let me know I love you. "The boy again taught the engagement ring girl. A few years later, the girl laughed again. This is a silent laugh of silent love.
