Can someone tell me about the male lead in this? Is he a green flag to the mc?

Nothing here is a green flag. Nothing. There's no green, there's not even red. This whole mess is a black flag

(The ml doesn't abuse the mc if that's what you're asking)

Wow you explained it so well

The ml who doesnt abuse geom is prob a yellow to green but the rest black

Honestly, the ML is the only patch of green you'll see for miles in this story. The MC himself isn't one.
