[When he was eight years old, his father Wei Jiangyang passed away suddenly.
Wei Ruan was brought to Kyoto by his vain and selfish mother Ruan Fenfang.
As compensation for the deceased, Lan Yu doted on the little girl and became the respectful "Uncle Yu" she called her.
In the eyes of others, she is lively, cute and carefree.
Only Wei Ruan herself knew that from the harsh treatment in the countryside to the bullying in the city, she had always been alone.
The Blue Domain is the only light in her gloomy life, and it is also the delusion she hides in her heart and dare not express it.
Until that year in college, in order to save him, the two accidentally crossed the line.
She thought it was an opportunity, so she approached him desperately, and Lan Yu's long-repressed feelings gradually emerged...
But when she knew everything and asked him about his choice, his hesitation made her heart completely calm.
Then she disappeared.
Blue Domain is crazy.
When he finally found her, he got a sentence: Uncle, who are you?
He was completely panicked.
He wants to say he's not an uncle, but...
Now that he is no longer an uncle, why did he go there so early?
