Omega has history of being abused by someone close in his life. Rape does not happen between the lead omega and alpha, and the lead alpha does everything he can to be the opposite of the omega's previous experience. Tries to get him out of that situation. Very sweet. Very compassionate.
Omega lead assaulted by Alpha (that is not the ML). Happens when they both experience first heats at school cuz they're fated partners. ML is not MC's fated partner. Second pairing is shit alpha x another omega, where shit alpha learns the error of his ways and is forced to repents for his sins. Good character growth. (Also one of the first omegaverse manga that ever received a printed volume!)
Points at which Alpha ML attacks Omega MC without her consent, and while MC is clearly in emotional distress. Not "justified" but it is explained that they had totally different POVs on what their relationship was.
Alpha on Omega repeated assault and harassment at school. Omega explicitly attempts to resist and reject. Alpha does not give a singular fuck. Infuriating to read if you aren't into that.
Early sex between Alpha ML and Omega MC is questionable consent with manipulative ML behavior. Later on, there is an attempted assault on the omega by a domineering shit-stain alpha who has also assaulted other omegas. The assault does not succeed.
Non-con? In a HypMic doujin? Grass is green, sky is blue. You know what to expect from that.
