the idea of the novel is good and grammar is also nice, it's just that the flow of reading breaks sometimes due to the wording.
overall I like it.[img=recommend]
also I feel like that the more I know about the mc the more I'll get immersed in the novel.
maybe an auxiliary chapter about the characters info or a side chapter that explains his sickness.
(if it hasn't been explained in the novel. I haven't read above 50 chapters yet).
