The very first line of this section hits you with something that seems minor but actually carries so much thematic weight: "Almost every student had a vial of Regeneration Factor on their desk. Only the siblings' desks were completely empty. What a lavish display. Even Cen Wu felt a little heartbroken watching it. The price Lu You had paid just to make friends was way too high."
Let that sink in. Every single student has this miraculous substance that can regenerate injuries, and the Cen siblings don't. Not because they can't afford it, but because Lu You spent all her family's resources trying to buy friendship. The Regeneration Factor becomes this symbol of everything wrong with this world — it's a status symbol, a social currency, a way to belong. And Lu You, in her desperation to be accepted, gave it all away.
The empty desks of the Cen siblings contrast sharply with the lavish display around them. They have nothing material, but they have each other. And honestly, that's the real theme here — what does it cost to fit in, and what do you actually gain? Lu You gained nothing. She's still isolated, still fake, still running to the principal the moment things get difficult. The Regeneration Factor couldn't buy her real friendship.
There's also the symbolism of the desk being turned into a barbecue grill. Food, cooking, warmth — all twisted into an instrument of humiliation. The bully takes something meant for sustenance and turns it into something that burns. And Cen Yuxing's chair being covered in glue — something meant to sit on, to rest, becomes something that traps and humiliates. These objects of daily life are weaponized, which speaks to how the world around these kids has been corrupted.
The surname reveal at the end — Cen Wu and Cen Yuxing sharing the surname Cen with the Base Chief Cen Jiao — is also thematically rich. Blood ties, family name, the idea that identity and belonging come from who you're related to, not what you can buy.
