He is her nominal guardian and she is his nominal daughter
Twelve years ago, she was left alone by her parents.
Twelve years ago, his family was ruined because he missed his elder sister-in-law.
She, struggling in purgatory, and him, trapped in darkness, met in the triangle of life.
She is obsessed with everything about him, following him closely and refusing to let go; he avoids all feelings and dare not reflect them one by one.
I'm a stupid person who can't do anything except write articles. I don't know how to organize beautiful copy, I don't know how to draw super beautiful pictures, and I don't know how to speak nice words. If you don't mind, I can stay for a cup of tea. I will try my best to tell a story to the guests to relieve their boredom.
