I Have Been Planning on My Gentle Foster Sister for a Long Time

[Age difference of ten years] [Pseudo/Orthopedics/Department] Copywriting: Falling in love with his biological sister was the most rebellious thing Yu Yang had ever done. Others were young and ignorant, but she was suffering from the shady. On the day after the college entrance examination, my mother confessed: "Actually, your sister was a child adopted back then." - Yu Yang learned the tricks on the Internet and lured her deeper step by step: Claiming that he couldn't get used to living in the university dormitory, he wanted to move in with her coquettishly, but Yu Shiyou agreed. With the strength of the wine, she fell into her arms and asked for a goodnight kiss, but Yu Shiyou didn't push her away. Deliberately releasing the news that he was dating his girlfriend, Yu Shiyou flew back overnight to intercept her, blocking her at the entrance and asking who she was. … Thinking that boiling the frog in warm water was effective, Yu Yang mustered up the courage to confess his feelings. But in return he received a coldness that women could not avoid. - After two years of separation, Yu Shiyou rarely saw this sister again. Unexpectedly, I received a call again, but it turned out that the other party had an accident and fell into a coma after being sent to the hospital. After rushing to the hospital, the usually calm woman became confused and spent a night outside the ICU, finally willing to face what she had been avoiding for a long time. A few days later, Yu Yang woke up, looking confused and forgetting all about her: "Excuse me, who are you?" Yu Shiyou was silent for a long time, with complexity in his eyes that Yu Yang couldn't understand. "I am your... Sister." She originally didn't want to escape anymore, but she had no chance.
