I feel like people deem anyone "nice" to the uke as a green flag lol
Like, I get that people are desperate for bl couples that just don't ever have any issues with one another outside of petty squabbles, I just personally feel like doing that is diminishing to the work as a whole. Boiling the plot down to "is the seme nice or not" and using that as a metric is childish and the easier thing to do.
Even if Guwon is nice to the mc, it doesn't mean he couldn't be psychotic or generally a bad guy given the setting. I've read plenty of series where the seme is seemingly nice to the uke, but in reality they are a scumbag and their kindness is reserved for the uke. That doesn't make someone a green flag if you ask me lol
At the cover art and Guwon and expect this to be wholesome or "green flag seme" then you might need to have your head checked lol
