I loved the premise here, and it does explore the rarely mentioned part of ABO universe, the recessives, but boy, does this story jump in all directions and ultimately almost gets nowhere. Mad scientists who are also high school kids (WTF!! The bottom's former boyfriend, who is barely older than him, is also a scientist that did groundbreaking scientific research... When he was 16 years old?? You see, the manhwa has several of such moments that don't make any sense...), power hungry company CEOs, dynastic tendencies and whatnot... Not extremely original, but as I noted, the very basic premise, with a pretty dominant omega who is mega popular and a recessive alpha who was bullied, was what hooked me in. The tables were somehow turned, and both the seme and the uke were well written chars, both are flawed but both are very endearing. One of the problems of this manhwa is that the focus on the beginning, which was the seme waiting for the uke for 10 years, but slowly starts to grow out of it, was fantastic, but then all the company drama comes in and it becomes a semi thrilled. Uke's former boyfriend was a fantastic char in the making (the way he goads uke into a photo session was excellent, but this was also completely forgotten), both impressive and completely bonkers, but then the make him a crazy mad scientist and he ends up completely irrelevant to the story by the end, which was a big, big omission IMHO. The secondary couple didn't really hook me in, I didn't are for them although the seme had his good moments.
Overall, if this was more emotions based and less soap opera drama, if the put the focus on the seme waiting and the uke fighting his grandfather (his character was too black-and-white, he needed more nuance, some explanation to why he's behaving like he does. Maybe he's a alpha supremacist or something, this way he just ends up a one note bad guy.) Uke's mother also deserved more screen time and her story developed in more detail, I wanted to know how she fared with a domineering father who wanted to limit her reproductive choices, and what happened to her late husband and uke's dad?
Overall, while this way okay, and the art was pretty good, I felt the wasted a pretty good premise.
