A Lonely Bird in the Golden Cage

Canary is a kind and empathetic girl and she helps whoever is in need of help. She holds a compassionate heart. She empathize with a boy, Hyacinth, in her high school but she doesn't know that he would gradually become obsessed with her. Moreover, Hyacinth has a psychological disorder and being with Canary is his only cure. He uses any means necessary to get close to her. When they grow up, he tricks her to marry him.
"Hyacinth! Upon your condition, I am paying the debt by marrying you but do keep in mind that I don't love you."
"I will make you love me gradually."
"I will never love a hypocrite like you."
Hyacinth's eyes turns fierce and it seems like he has become a totally different person.
"I don't care what you think or feel. You belong to me. Even if I cage you or set you free is up to me."
"I am not a property for you to own! I am a human being!"
What games will the 'fate' play with them? Will Canary be forever locked in the golden cage? Or will she able to break free the chains of obsession and find her happiness.
