Ash & Koi met in high school. Ash was popular ice hockey captain - the jock. Koi was shy timid guy. Both fell in love but circumstances kinda separated them got 10 yrs .
Meanwhile Ash as a dominant alpha was supposed to regularly remove pheromones via sex or medically which he refused as a punishment to Koi in a way..and kinda went mad...the whole self destruct in love situation.
After meet again as Koi finally seems him out ..but there's loads of angst and finally they do end up together.
Ash's character changes completely from this sweet boy to the cold personality he is kind of.

I read the novel of Grayson’s parents… very the speechless, the angst, the craziness. How i pictured them and how its drawn here, very different. Eventhought that is said, looking forward to this manwha.
