(VERY MAJOR BIG SPOILERS PROCEED W/ CAUTION)
This is just from my rough memory so forgive me if anything is wrong but:
- ahn yoonseung dies, kim kiryeo experiences grief for the first time
- kim kiryeo (og) got his money stolen by his mom that abandoned him 2 times; while working to supply his mom’s gambling addictions, he encounters a monster and gets a leg injury that sinks him in debt. He tries to seppuku thereafter
- lemming (the alien in kim kiryeo’s body) was basically exploited by the entire alphauri planet and race for his whole life of 6,500 years; imagine being forced to work non-stop for that long, pumping out every last source of magic and energy you have without stopping, sleeping, or eating because your people programmed you, a living being, to live like a machine
- lemming’s only friend, another alphaurian, died saving him and ultimately supported him in succeeding in the reincarnation magic
- kim kiryeo almost dies and traumatizes everyone who saw that
- kim kiryeo gets diagnosed with lung cancer and it’s at the 3rd or 4th stage (?) and he found out only after becoming s-rank so it became harder to treat
- not rlly a plot point but an observation i find interesting: it is not that lemming is incapable of feeling emotions, he only knows a select few which are mostly negative emotions like fear, anxiety, stress, exhaustion, and anger because he never really felt lasting happiness and joy in his 6,500 years of living, mostly due to how his race modified him to be an ‘efficient’ machine for work
- big lesson of this story is f#ck capitalism
Everything here may or may not be in the right order, and I definitely missed some stuff, but yeah that’s what i mainly remember

(DO NOT READ IF YOU’RE EASILY INFLUENCED BY REVIEWS)
Dear manhwa readers, enjoy your time while you can. I read the novel some months ago and to kill time, I tried rereading the manhwa since I’ve read everything on my list. This is not a drill, though. Don’t be scared and miss out on this peak. I definitely recommend the novel for the best experience, however it sort of is more serious.
It’s safe to say that you guys should definitely appreciate how chill things are right now. I get so sad seeing the first chapters of the manhwa, as I get reminded of how our baby Kim Giryeo just wanted a peaceful life.
I can’t stress enough how much you guys will treasure this green little alien thing as more chapters get released, so be happy while he still is. ╥﹏╥
