Su Ruhua could still remember the shock, indignation, and jealousy that came upon her when she was about to carry the baby-like Su Man, whose growth had been stunted, into the back garden of the Su's mansion to play with when Su Ruyu brought the three herbs back.
She clearly saw how her typically cold younger sister had a gentle smile on her face, brimming with happiness, as though she were in love.
Both sisters were very close to each other and would tell the other anything on their minds. She liked Mo Shitian, but she was unable to tell Su Ruyu because Mo Shitian rejected her. She felt terrible about it and still needed time to recover from it. If it were something happier, she would naturally tell Su Ruyu so that her younger sister could share in her joy.
She could tell that Ruyu was in love.
