It is a story of silent love between a boy and a girl from a middle class family in Bangladesh. The girl's family refused to accept the boy in the traditional way. Naturally, the girl's family tries to convince the girl that the boy does not have a very bright future, that having a relationship with her is nothing but foolishness.
Under pressure from her family, the girl says to the boy, "How deep is your love for me? You do at least one thing. Besides, no one will accept our relationship. " The boy can't find an answer. He is silent. The girl gets angry and leaves. Even then, the dreamy boy dreams of their future, somewhat like Anjan'da's song, "In this black-and-white city of lies, yours-my red-blue family."
The boy decided to go abroad for higher studies one day. Just before leaving, he says to the girl, "I may not be very good at words, but I know I love you very much. Even then, if you want, I can tell your family about your marriage. Are you willing to spend the rest of your life with me? "
The girl agrees with the boy's determination. The boy persuaded the girl's family. Then their engagement takes place and it is decided that if the boy is established and returns to the country then they will get married. The boy then left the country.
The girl started working in an office. Meanwhile, the boy is also busy with his research work outside the country. Even then, in the midst of hundreds of engagements, they communicate their feelings of love as much as possible through phone and e-mail.
One day the girl had a road accident on her way to the office. Sense back he sees that she is hospitalized and realizes that she is seriously injured. He sees his parents by the bed. When the girl realizes that her mother is crying, she realizes that she has lost her speech. According to the doctor, the girl has become dumb for the rest of her life due to a brain injury.
Once the girl recovered a little and came home. Meanwhile, the boy keeps calling her but the girl says he has nothing to do. The girl made a decision one day. She no longer wants to involve the boy in this conversation-less life.
As a result, one day he wrote in a false letter that he could no longer wait for the boy. The girl then sends her engagement ring with the letter to the boy's address. The boy sent thousands of e-mails to the girl but she did not get any reply. The boy calls hundreds of times but the girl has no choice but to cry silently.
One day the girl's family decides to move to a new environment in another area so that the girl forgets these bad memories and stays happy.
In the new environment, the girl learns "sign-language" and starts a new life. One day after a couple of years, one of the girl's friends came here and told the girl that the boy had returned to the country. The girl requests his girlfriend so that the boy does not find out about her condition in any way. Then a few days later the girl's girlfriend left.
One more year later, the girl's girlfriend came to the girl with an invitation card. The girl opens the card and sees that it is the boy's wedding invitation card. The girl is surprised when she sees her own name in the place of the bride. When the girl asks her girlfriend about it, she sees the boy standing in front of her. The boy then uses "sign language" to tell the girl, "I've spent a year's time to learn sign language. Just to let you know that I've not forgotten our promise. Let me have the chance to be your voice. I Love You. " Saying this, the boy taught the girl the engagement ring again. A few years later the girl laughed again. It's like a silent smile of love.
