I really think these robots are cyborgs or at least have a human brain or something. They feel really complex emotions like desperation, Earl literally broke himself to essentially escape being kidnapped to go back to a human. Callum straight up feels jealous and they all have a level of shyness to them as well which makes no sense since robots, regardless of programming, wouldn't see any use in being shy. Also, the robot who eats burgers seemed to have a flashback of being shot, possibly killed, and acts kind of meta for a robot. This story is so interesting
Dojin and Hyesung need couple's therapy. I'm still convinced that Hyesung hasn't fully accepted that he's an omega. Especially with his past trauma and his trauma with Dojin. And yes, there's trauma in their relationship. Their relationship reads like those movies set in the 50s and 60s where two young adults hook up, the girl gets pregnant, and their families force them to marry. You can tell each of them has feelings for the other but like damn, get it together.
Like oh my god, it's so nice to see an alpha that actually wants his partner to be happy. He's being very considerate of the fact that this is all new to Riku and he doesn't want to move too fast. He's not possessive to the point where he's controlling, he's just protectively possessive. Not to mention the fact that he's not telling Riku that he can't live like he normally did before he found out he was an omega, nor is Keiki treating him any differently. This is a great ABO manga
Hopefully he stays this way!
