even if (джен)

The first time they had this argument, Lu Guang was still only nineteen years old. He and Cheng Xiaoshi muddled through their abilities with curiosity and bravado. The only thing Lu Guang was afraid of was drowning, and it was abstract.
The first time, Lu Guang grumbled at Cheng Xiaoshi. I’m tired, asshole, he said. Can’t you give me a break? Cheng Xiaoshi said something tone deaf–but you don’t even have to dive, you can just sit there and tell me what to do, it’s easy for you–and at that, Lu Guang stomped up to the bedroom, muttering it’s useless trying to argue with you to himself as he locked the door behind him. He burrowed himself angrily in the bedsheets and didn’t emerge until Cheng Xiaoshi cooked an entire apology dinner.
I’m sorry, Cheng Xiaoshi said quietly when Lu Guang stuffed his mouths with softened carrots. Do you–do you want to talk about it?
