Being on the same family registry in China is not reason enough. A friend was explaining some of Chinese culture to me & said historically, it wasn't uncommon for gay couples to be "adopted" into the family as a way to have socially acceptable gay couples...to an extent. Being LGBTQ+ is dangerous in China.
The fact that they grew up together as brothers, though, is a bit...much. It's not like the stepsisters in Citrus, who didn't meet until high school as complete strangers.
This is why i skip side couple and always focus on the main couple . Anyways atleast they knew since they're a kid that they're not related otherwise it'll be weirder lool.
