Of Green flag omegaverse like the only thing allowed anything near red flag is the first accidental non con s3x. Like love shuttle.
This one is green but there is a MENTION (no scenes) of past sexual assault (in conversation) to explain the ML's resistance to alphas: https://www.mangago.zone/read-manga/oredakeno_senzoku_alpha/
The alpha in the relationship is a green flag all the way!
This one is also green all the way!
