The art is phenomenally, the story pacing and telling however ruined it for a lot of people. The ending didn't clear things up, a lot of stuff was just left unanswered. I don't know if this was due to translators switching every few chapters or if that just is how the story is paced, but sometimes less is more.
Why were people trying to continuously assasinate Keith? Why did he have to buy jewelry for his dad (?) or whoever that Angel person was? Why did Yeon constantly end up in the hospital and faint all the time? Why did Keith's pheromones make him so dizzy? This Omegaverse is so different from all the others, there needs to be more time put into explaining how it works. It's hard to enjoy a story as a reader when everything is rushed and messy and the characters are just unlikeable. Shame because this had a lot of potential.

This is one of the few yaoi mangas that genuinely made me cry. Setting aside the beautiful artstyle, the story telling and the flowing pace, god. This is just so incredibly healing. The Seme was so gentle, always waiting and asking if it's okay, and oh my god, the ending. T h e e n d i n g. When he said he waited because you can't possibly love someone without loving yourself. Fuck man. When I realized the title "The one and only" wasn't referring to the love for someone else, but the love for yourself, I burst into tears. Definitely will be thinking about this phrase a lot. Absolutely beautiful from beginning to the end
I adored this so much, both characters are so enjoyable and amazingly written, their relationship progressed so well and the humor made me laugh a ton. Absolute dorks, I treasure them with all of my heart (づ ̄ ³ ̄)づ
