All the content in the three volumes of the book resemble each other.
If you resemble someone who's cruel, you, well, you resemble them. Maybe you're really mean too. I guess only you can know that. But you do look like that other guy...
This is a jukugo word that uses the on'yomi readings of the kanji. You didn't learn this reading for 似 yet, so here's a mnemonic to help you:
Which cruel guy do you resemble? Jesus (じ), of course. I mean, you look just like him. Look in the mirror if you don't believe me. Look, there he is. Wait, what do you mean he isn't a cruel guy? I guess you're the cruel one then. Sucks to be you.
