started reading the novel after manhwa and I'm kind of surprised rn how different they are? more so in tone but the manhwa also left out a lot of things and changed some details for the sake of comedy.
by left out things I mainly mean mc' flashbacks. which is hella weird bc those are important for mc character and bonding moments with kim nari. for example in one ch mc remembered his life in orphanage and how the biggest kid bullied smaller kids there. that boy took all the blankets from them and even food prior to that memory so mc was starving and freezing. mc mentioned then that last winter thanks to that 4 kids died and wondered if he would be next this year. so in the age of 8 he killed that person in his sleep with a pen. that's why he was kicked out of that orphanage (not bc of murder since it's slums but it was used as an excuse to get rid of another mouth to feed). and later kidnapped with other kids.
the other flashback that was kinda important was in the scene with kim nari (manhwa's flashback with kids ganging up on her). in those he explained that since they were chimeras created for battlefield those that ranked low in competition would undergo high risk experiments (yk basically death). so fighting for their lifes kids would gather in groups to gang up on higher ranks to inflict damage that would left them disqualified. just like in the orphanage researches didn't care and only blamed the victim. since mc was always the 1st in rank he was left out while all other kids gathered in groups. kim nari was the same but while mc didn't care she was hurt by that. mc also remembered how one time 9 kids ganged up on him like that after what he broke their legs with the thread.
there were also flashback where when one instructor tried to lay a hand on him and the researcher stopped him explaining that those instructors who touched mc where found maimed the next day. that instructor was replacing the man who was left without an eye. mc picked his eye with a spoon in his sleep.
and that's like only 10 chapters. considering that ch 17 of manhwa is around 30± of novel there must be even more things left out.
