Prolly alcoholism. My guess is the doctor is saying he's an alcoholic which is causing him to be more lethargic, depressed, and the sleep walking. That can lead to more problems like liver cancer, liver failure, or even alcohol poisoning and the like. I just hope that he doesn't take back Jaegeng just cause he'll help him with his health, after all he's (Jaegeng) pretty much a large chunk of why he's so dependent on alcohol now, after granny dies I just hope he leaves Jaekyung and live his life freely for the first time. But alas, looking back on the author's past works, I highly doubt that'll happen. Anyway, considering the author's past work, the pattern will be: 1. seme will still be full of himself and be like he only likes him for sex and he doesn't really have romantic feelings 2. Uke will be firm in being cold which will make Seme realize his feelings for him 3. Short chasing arc of seme where they will also show his tragic background why he's such a jerk 4. Something big will happen where Seme will do something for uke which will make him go soft and forgive seme. 5. They get together and suddenly seme has a 180 on his character where he's such a sweetheart but only mostly towards uke and people around them will notice it and talk as if that's the best character development ever.
