I see what you're getting at, but toxic behavior isn't always in your face and is to hurt another person. Some ppl are toxic without even realizing it. Dojin isn't tied to Hye-sung tho, so what's so who's really in the wrong? Hye-sung is bc he has nowhere to go. The omega believed he was an alpha his whole life (IS attracted to omega's) but was forced to give birth & now has to deal with all these conflicting feelings about himself. Tell me, when Dojin asked Hye-sung how he was feeling about all this? Dojin literally shut him down & refused to accept the fact that Hye-sung wants to at least experiment with an omega.

Some people here ganging up against dojin. You put yourself in his shoes. When in fact since the very beginning he was the one who was very understanding in their relationship. And hyesung? I don't know. I don't even know if he really loves dojin. Or is it just the money.
Don't you ever tell me that u people don't get jealous when you see your partner looking at other people like how hyesung did. Regardless of gender, specially when he/she has a past of liking a person like that and has a gender identify crisis.
