After an hour of mental struggle, Rena finally took the alarm out from the box again carefully. Then, she set a 5.30am alarm according to the instruction manual before placing the alarm clock carefully on her bedside table. She extinguished the oil lamp, and lay back on her bed.
Listening to the clock needle's soft ticking sound, Rena, who was tired after a whole day's work, quickly fell asleep.
Ding~!
Early next morning, Rena was woken up by a loud and clear noise. She looked around her in a shock when she sat up in bed. She only realized it was the alarm clock ringing at the bedside after a while. She held it up to have a look with the faint light coming in from the window. The needles were pointing at 5.30am.
