So I read the novel and I'm super disappointed. I loved how the story started and how heart wrenching it was, but it kind of turned into a drag, with the author not taking the multiple chances to end the story and stretching it out to be some torture fest for the seme. Which, don't get me wrong, was super satisfying for me because the seme was such a douchebag, but there comes a point where it's just overdone and tiring.
In the novel, the uke finally packed his bags and left for his (and seme's) hometown. The doctor chased after him, and insisted on staying and looking after the uke. The uke never really came to love the doctor, but he was grateful and full of guilt that he can never return the doctor's love. The seme went crazy trying to find the uke and developed a heart problem. When he finally found the uke, the doctor refused to let him see uke and uke didn't do anything either. This is where the story started going downhill. The author seemed really self indulgent in how they seemed more interested in torturing the seme as much as possible and for as long as possible rather than developing an ending that was fitting, for all their personalities. The doctor was in love with the uke for no reason at all, and seemed to exist as a roadblock more than anything. And because he refused to let the seme see uke before his death, and uke was the type to not fight these things, uke eventually passed away in loneliness and sadness. And yes, the seme was shite to him the few years before this, but neither were given a chance to reconcile because of the doctor, and the seme was doing everything in his power to see uke and make it up to him. The doctor also didn't inform the seme of uke's death until an entire week later, and told seme what uke allegedly said before he died, which was that the uke never wanted to see the seme again, neither in life nor in death. Absolute asshat move on doc's part. We never find out if uke actually said that or not, but seme was tortured by it. He became an alcoholic, seeking memories of uke in his dreams, refused to accept the reality that uke was dead and gone, waited for uke to come home every night, self-harmed, and with his friends' intervention, went on a trip around the world. But he would forever feel tortured and never find solace in anything.

Like I said, the author sort of went on a trip torturing the seme as much as possible, and it went on for way too long (honestly it felt like 3/5 of the book went to describing how tortured the seme felt). There were a lot of points where the uke could have avoided a lot of pain and problems if he had just spoken up instead of expecting the seme to understand everything and act accordingly (hello, he's not a mind reader), and while the seme definitely made many unforgivable mistakes, the author makes it seem like every single issue between them was the seme's fault. Overall the book was overdramatic and overindulgent on the author's part. Which is super disappointing since it had such a promising start.
