Isaac was studying psychology, so he should have already known about Second Brother's personality traits, but he had been too immersed in the shadow of that line "I don't want a baby" and hadn't analyzed the problem carefully.
Without waiting for Second Brother to speak, he immediately started analyzing the situation.
"You told me a while back that you don't like kids, but in fact, you wanted to give me time to study and didn't want me to work too hard, right? You're so good to Zoe, how could you possibly not like kids? How could I be so foolish today..."
With just one sentence from Second Brother, Isaac thought of so much more—that was their tacit understanding.
"Compared to Second Brother... I don't even know what's wrong with me," Isaac said looking at him with guilt.
