My brother poured sleeping pills into my sister's tea and smashed her while she was transferred out

In this scene, a brother and sister are having a heated argument. Suddenly, the brother takes out a bottle of sleeping pills and pours them into the sister’s tea. She takes a sip and starts to feel groggy and sleepy. The brother then carries her to the bed and gently lays her down. As she falls asleep, he grabs a blanket and tenderly wraps her up. He then kneels beside her and tenderly kisses her forehead, whispering words of encouragement and love. This is a beautiful moment of love and care, where despite their differences the brother shows his unconditional love for his sister.
