恋爱三年了，林和紫准备在秋天结婚.紫在新房里架了一台缝纫机.要把从布料中心淘来的一块粉色的缎子做成窗帘.快做好的时候，紫的手指突然被针尖扎破了，不由失声叫了出来，林心痛地用窗帘包住她受伤的手指。放开手，那块窗帘染上了一块粉红色的血迹.紫听老人说过，办正经事的时候，见血是不好的预兆，她的心便有了细细毛毛的折痕.端详了那块血迹很久，用针在上面绣了一只粉红色的蝴蝶.
窗帘终于做好了，林站在椅子上准备将它挂上去，却突然摔下来，昏倒在地上。林患的是癌症，医生要紫做好心理准备，说可能性最在的是林就此昏睡不醒，变成植物人.那以后，紫每天除了照顾林，就是祈祷，希望仁慈的上帝救救她生命中不可缺少的爱人.一天紫在梦想中仿佛听到有人说：如果你愿意变成一种动物三年，你的爱人就可以醒过来.好，我愿意，只要你能救他。请把我变成一只蝴蝶吧.紫感觉自己的身体变得轻盈，然后两只手臂变成了一对翅膀，轻轻一扇，就飞上了天空.这真是一个美丽的梦。忽然紫听到护士夕的声音:他醒了，他醒了。他醒了，紫想问她是不是林醒了？却发现已经不能发出声音了，再一看自己在半空中......原来她真的变成一只蝴蝶。
紫放低翅膀，停在林病房的玻璃窗上，看到林坐起身，四处寻觅，喊出的第一个字是：紫。紫的心里一下快乐起来，她拼命地扇动翅膀想引起林的注意，她想他一定会认出她来......只是可惜，没有人会注意到一只蝴蝶振动翅膀的频率，包括林.原来，世上最远的距离，不是天各一方，不是生离死别，而是我就在你面前，你却无法认出我。
林傻傻地坐在床上发呆，护士夕劝他出去走走，但林象听不见一样，没有任何回应。一愁莫展夕发现了紫，指着她对林说：你看多漂亮的蝴蝶啊，我们出去看蝴蝶吧.蝴蝶想到了那个在窗帘上绣蝴蝶的女子，林一下从床上跳下来说：我要去看蝴蝶.接下来的每一天，夕都会陪林到病房外的花园走走，有时候在椅子上坐下来，林对夕讲他和紫三年来一起走过的点点滴滴。说到动情处，林会忍不住声音哽咽地问夕：紫到底去了哪里?这时，紫都会飞落到他的肩上。
林的身体一天天好起来，而紫却不能在陪伴林了，因为秋天来了，她必须飞到另一个温暖的城市去，不然她会冻死的.在他们本来要结婚的时候。
第二年夏天，紫迫不及待地飞到这个城市。正好听到林和夕的谈话，却不再是有关自己的内容，而是一些逗笑的轻松话题。紫看到林不时偏过头看夕，那眼神里有令紫心悸的炙热。紫感觉一阵眩晕，轻轻地落在林的肩膀。她多想能象从前那样依在他的胸前，听他的心跳。突然，林伸出手臂揽住夕的肩膀。紫的心中一阵锐痛。尽管那只是颗小小的蝴蝶的心脏。夕一偏头，看到落在林肩膀上的紫，轻轻地惊叹：多美的蝴蝶啊。林转过头，一下捏住了紫的翅膀，将紫拿到夕的面前说：喜欢吗?我把它做成标本送给你。紫心头一凉，但她不想挣脱，哪怕是死在爱人的手下，为的是取悦另一个女子，她也不想逃走，因为是无论做一个女子，还是做一只蝴蝶，也无论生死，她的一切都会为这个男人而存在。不，快放了它吧。如果把它做成标本，它的爱人找不到它会伤心死的。夕说，你真是一个善良的女子。林看着夕的眼睛。紫看到那双眼里折射出的光芒，刺痛了她，以至于在被林松开双翅后忘记了飞翔，一下子跌在草地上。夕：哎呀了一声，从地上捡起紫，把她捧在手心里，对林说：看，你把它弄痛了。林说：它只是一只蝴蝶，怎么会痛呢？看啊，蝴蝶哭了。夕看到紫眼里有很小却晶莹的水滴在闪烁。而林已无心看这只蝴蝶，他侧过身轻轻地吻夕的脸庞，紫翅膀一振，飞离了这个城市。泪水竟然落了一地。
第三年的夏天，紫都不想在到林的城市里去了。但她还是忍不住去了。她飞到曾经和林准备结婚的新房，第一眼就看到自己绣了蝴蝶的窗帘，心尖滑过一丝疼痛。门开了，紫看着夕挺着大肚子走进来，林在后面呵护着她．紫静静落在窗帘上那块血渍绣的蝴蝶上，看着林将夕扶坐在沙发上。“看，多神奇的蝴蝶！”夕发现了紫，指给林看，“它正巧落在那只绣的蝴蝶上。”林走到窗前，紫闭上眼睛，等待林用手来捉自己。最爱的人啊，我愿意承受一切，只要是你赐予的。好久，都没有动静。紫睁开眼睛，她几乎窒息，林蹲在她的身边，凝视着她。他的呼吸扑面而来，那么久违，那么熟悉，那么轻而易举地让一只蝴蝶流泪了。
“我看到了，蝴蝶真的会流泪。”林的眼里全是迷离，伸手去抚摸紫的身体。紫轻轻地扇动翅膀，转过身将脸在林的指尖上轻轻地磨蹭。“我觉得，它像一个人。”不知何时走到林身边的夕轻轻说：“像一个人？”林震了一下，回过头看夕。夕的眼眶湿了，咬着下唇点点头。林转过头看紫，正在这时，紫扬起翅膀飞出了窗子。
三年终于过去了。神准备将这只可怜的蝴蝶变回自己，紫阻止了神，说：“我不想变回人去打扰他的幸福了。”
这年秋天，夕为林生了一个女儿，取名“蝴蝶”，但他们再也没有看见过那只会流泪的粉红色蝴蝶。

爱，是奉献，是牺牲，是为他想，是给他自由。

Crying Butterfly
Lin and Zi had been in love for more than three years. They prepared to get married in Fall. Zi setup a sewing machine in the bedroom and managed to make a curtain using a block of pink cloth. Unfortunately, Zi's finger was stuck by the needle when the curtain was almost done. Hearing Zi’s screaming, Lin quickly wrapped her finger with the curtain, which left a pink blood stain. There was a saying that seeing blood before wedding was a bad sign, would lead bad luck. So Zi could not drive away the thought that something bad would happen. She looked at the blood stain for a while and embroider a pink butterfly on it.
The curtain was finished. Lin stood on a chair and tried to hang it on. All of a sudden, Lin fell off on the floor and lost his consciousness. Lin was sent to hospital. The doctors told Zi that Lin might sleep forever and might not gain his consciousness back anymore because he had a fatal and incurable disease. Apparently, Lin would be in vegetative state forever. From then on, Zi prayed for Lin everyday except taking care of him in the hospital. She Hoped that God would save Lin, her lover, who was the most important and precious one in the world.
One day, she seemed to hear that somebody said to her in her dream:” If you'd like to change yourself to an animal for three years, your lover Lin would wake up." "Great, I 'd love to do it as long as you could save him. Please turn me to a butterfly." Zi felt her body was getting lighter and her arms changed to wings. She flied into the sky. This was a wonderful dream. Suddenly, Zi heard one of the nurses was shouting happily:” He is awake. He is awake." Zi wanted to ask if Lin woke up. But she could not speak anymore. She looked at herself flying in the sky. She realized that she was really a butterfly now.
Zi retracted her wings and stopped on the window. She saw Lin sat up and tried to look for her everywhere. The first word Lin spoke out was Zi. Zi was excited. She shook her wings eagerly and tried to get Lin's attention. She believed Lin would recognize her. Unfortunately, Lin did not notice the butterfly. The farthest distance in the world was neither we were on the other side, nor we were separated by death，but you could not recognize me even I was right in front of you.
Lin was sitting on the bed absent-minded. The nurse Xi persuaded him to walk for a while. But Lin seemed to hear nothing and did not respond. Xi was frustrated. She saw Zi, the butterfly, and said to Lin:"How pretty the butterfly is! Let's go and enjoy the butterflies outside." Lin jumped off the bed excitedly and said:” I want to see the butterflies." On the following days, Xi walked with Lin in the garden. Sometimes they sat down on the bench and Lin would tell Xi about the life, which he shared with Zi. Sometimes Lin could not stop asking sadly:” Where is Zi on earth?" Whenever it happened, Zi, the butterfly, would stop on his shoulder.
Lin was getting better. But Zi could not be with him because the Fall was coming, when they were supposed to get married. She had to leave for a warm city, otherwise she would die from cold.
Zi could not wait to fly back to this city in the following Summer. When she saw Lin, he was telling Xi some jokes. Zi knew Lin would not talk about her anymore. Zi noticed that Lin looked at Xi from time to time. Zi could read the desire and care in his eyes. Zi felt dizzy and stopped on Lin's shoulder. How eager she was to lean on his chest, listen to his heartbeat like before. Suddenly, Lin held Xi's shoulders. Zi felt sharp pain in her heart, although that was only a little butterfly's heart. Xi turned her head and saw the butterfly on Lin's shoulder. Xi admired:” How beautiful the butterfly is!"Lin turned his head and held the butterfly's wings promptly. He gave the butterfly to Xi and said:” Do you love it? I will make it a specimen." Zi was depressed but she didn't try to fight. She gave up to flee away even she would probably be killed by her beloved man, even he would fawn over another woman. She told herself:" no matter I would be a girl or a butterfly, no matter I would be alive or dead, I would sacrifice for this man and all what I do would be for him." "No, please let her go. If you made it a specimen, her lover would be dead without her." Xi said to Lin. "You are so kind hearted." Lin looked deep into Xi's eyes. Zi saw the love flashes in his eyes, which hurt her deeply, and she even forgot to fly away and fell off to the grass after he set her free. Xi screamed and held Zi in her hands carefully from the grass and said to Lin:"See, you hurt her." Lin replied:” She is only a butterfly. How can she feel any pain?" ""Look, the butterfly is crying." Xi saw a tiny clear teardrop in Zi's eyes. However, Lin was unwilling to see the butterfly. He turned around and kissed Xi's cheeks gently. The butterfly shook her wings vigorously and left this city. Her tears dropped on the grass.
In the third year, Zi could not stop coming back to Lin's city again. She flew to the new house, in which Lin and she prepared to get married. The first thing entered into her eyes was the curtain, on which was embroidered a pink butterfly. She felt painful in heart. The door was open. Coming pregnant Xi. Lin was trying to protect her behind. Zi quietly stopped onto the blood-stained embroidered butterfly. Lin helped Xi to sit on the loveseat. "Look, how miraculous the butterfly is!" Xi found Zi and showed to Lin. "She is just standing on the embroidered butterfly." Lin walked to the window. Zi closed her eyes "My love, I love to bear anything as long as it is what you give me." She waited for a while but nothing happened. Zi opened her eyes and could hardly breathe. Lin was squatting beside her and staring at her. Zi could feel his breath. How familiar it was! It could easily make a butterfly cry.
"Yes, I see, the butterfly is really crying." Lin touched Zi's body gently. Zi shook her wings slightly and rubbed Lin's finger with her face. "I feel she is like somebody." Xi said gently. "She is like somebody?" Lin shocked and looked at Xi. Xi nodded with tears in her eyes. Lin turned around and looked at Zi while Zi unfolded her wings and flew out of the window.
Three years passed. God wanted to change the pity butterfly back to herself. Zi stopped God:” I don't want to be a human being anymore. I want them live happily after."
Xi gave birth to a baby girl named "Butterfly" in Fall. Since then, they never saw the crying pink butterfly anymore.
