Peeking through the heavy wooden doorway, Yu Qi saw a tiny, serious figure sitting at a large oak table, intensely reading a thick textbook with a remarkably focused expression.
"Bo Lin." Yu Qi called out softly so as not to startle him.
Hearing her voice, Tang Bo Lin instantly lifted his head from the pages and looked toward the door. His dark eyes immediately lit up with pure joy the moment he recognised Yu Qi. He carefully placed a neat bookmark between the pages, closed the heavy book, and stood up from his chair before walking over to her with precise, polite steps.
"Sister Qi." Tang Bo Lin called out, his voice full of warmth.
Yu Qi bent down and scooped the little boy up into her arms, noting how much he was growing. "What are you reading so intently today?"
"A textbook about the nervous system in the human body." Tang Bo Lin replied matter-of-factly.
"Do you actually understand it?" Yu Qi asked, genuinely impressed by his advanced choice of reading material.
