Heisuke slept so deeply. He didn't even notice when did his mother return home. The exhaustion from his previous job took a toll on his body without him realizing it.
At a quarter before eleven o'clock, Heisuke finally stirred awake. Mrs. Saeki was folding the dry clothes in a corner of the living room.
The lamp in the living room was not switched on. Mrs. Saeki only relied on the lights pouring from the kitchen that partially brightened the living room. Seeing how her son was so deep in sleep made her reluctant to disturb him.
"Mom?" His hoarse voice cracked the silence of the apartment. He tiredly rubbed his eyes, "When did you get home?"
He was shocked to see that he only had less than an hour to head to work. Usually, he had woken up long before that.
