Alphas are drawn to Omegas, and Omegas desire Alphas. This is the natural order, but Karlyle isn't your average Alpha. He doesn't crave every Omega he encounters—let's just say his situation is complex. Karlyle sees no reason to alter his ways, but when issues arise in his intimate life, his doctor proposes an unexpected solution. Try being with Alphas instead of Omegas. Karlyle finds this advice peculiar, yet the doctor insists he knows the perfect person to assist him. Enter Ash, who suddenly becomes a part of Karlyle's world, and Karlyle finds himself increasingly preoccupied with thoughts of Ash. Their bond transcends friendship but falls short of being lovers—how can such a relationship be categorized?

Well when you've read so many omegaverse stories which have issues like heat that forces the main characters into a situation to have sex (or rape and stuff unfortunately), it feels pretty refreshing to have a story that centres more on characters that consciously make a choice to engage in it, and see them fall in love.
Love the story, especially since the characters drawn are so pretty. The plot isn't the strongest draw of the story, but it's engaging enough for me to enjoy it overall.
Ash is generally a green flag throughout the series and is rather supportive of Karlyle, and they generally do talk in the series to solve their problems, well except for the last few chapters where Ash suddenly feels a bit more manipulative and yandere. But well, still liked the series overall!

I think it’s a good story. It’s pretty well written, has good pacing, and the art is pretty. But for some reason I just really didn’t like Ash. I can’t even explain why?? Something about him just felt so fake to me. Even by the end I still didn’t really like him. So, that kind of ruined it for me.
Since that’s more of a personal issue I can objectively look at this story and say it’s pretty good. Not the best thing I’ve ever read but not bad. I was hoping for more though, seeing how popular it is. I think it’s difficult to translate a novel into a manhwa, since lots of stuff gets skipped over.
None of the side characters got any development, it really only focuses on the main two. That’s not a huge issue, but because of that, some aspects became confusing. There were several times I didn’t understand how they knew certain people or why people behaved a certain way.
Overall, it’s good, I’d recommend it. But nothing really special.
Chapter 53 is my favourite. Gorgeous art. Sexual renditions are well-executed and intimate. Formal and straightforward dialogue that has an elegant touch. Anticlimactic resolution. Passionate and heart wrenching character interactions. Rough themes that bring out character development. Yields arousal and yearning. Recommended for those hoping to be swept away by visual stimulates.
Since the main couple was alpha/alpha, the story avoided most of the things about omegaverse that may be unappealing to some people. In fact, the same story probably could have been written without any omegaverse stuff. It was only used to bring the 2 main characters together and then to add marriage drama later on.
Overall I liked it, but Ash was definitely not a great guy before falling in love. I can tell he is sincere about their relationship, but he was very selfish towards partners. I feel bad for them. I don't think he suddenly turned into a better person, he's the same kinda fake guy, just now he's in love.
Sorry but it was such a overrated work, I expected soooo much and disappointed badly ... Apart from how overly dramatic it was , I find it super boring with too many useless repeating ott dialogue too , just filling space to drag story more when nothing going on ...
Im chapter 65 and I want to drop it bcz it's a simple love story dragged to hell when it can end simply in 30 chapters, u reading 50 chapter and it's felt nothing going on and i seriously can't stand/hate both Kyle and Ash , Carlyle is too good for both of those mfs ... Both of them using him and both dgaf about all sacrifice and pain he suffering.
It's funny how ash suddenly gaf and oh so in love when he clearly is a player prideful guy full of himself and u can easily said it's not the first time his hypocrite fake acts make a simple pitiful lonely guy suffered that badly.
from start he think about Carlyle as a strict fool and caused him so much pain ... And it funny he simply said ,I love u, as if that pitiful idiot have no option to accept it...
I wasted my time keep reading it and expected a better pace or a decent conclusion but I seriously getting more and more annoyed 😔
Whatever, dropped it bcz I seriously can't stand it...
I would say the art is beautiful and I'm a fan of big bottoms so I started reading with high hopes and it ended up being p much sweet webtoon which is always nice. Although there is some minor drama they end up resolving it fairly in a realistic manner instead of avoiding each other for like months for no reason which is nice.
I wouldn't say anything was super unique about the setting but I liked that Ash starts out a green flag and continues until the ending which is a great break from like secret yandere tops you know who they are in other series. Also, it's sweet how supportive he is of Lyle and his low self-esteem due to family trauma, and as a reader he becomes more confident slowly.
HUGE PLUS FOR THE ABILITY TO TALK ABOUT PROBLEMS (we're not talking about the last chapters)
