Not suicide!
Flashback
The twins were late returning from high school. They were just outside the Liu villa when Yukito said, "Damn, I forgot my book inside the car. Tomorrow is our test, and I need it to study tonight. You wait here, I will get my book from Uncle Mu."
Yukito went away, and Yukira was waiting for him, leaning against a tree.
He then heard loud noises coming from the villa. He turned his head and saw the balcony from below. He could only see partial silhouettes of Jinhai and Huian.
'What is happening over there?' Yukira frowned. 'Damn, is it that Mrs. Liu insulting my Nee-chan again!? Can't she take a rest!"
He stepped forward, and then suddenly, he saw Huian climbing on the balcony's railing.
Yukira widened his eyes in shock.
"What is she doing!? Is she crazy!?"
Then after a few seconds, he saw Huian lose her footing, and she was about to fall, but Jinhai caught her hand in time.
Yukira let out a huge sigh of relief.
