i like how people complain about bestiality or whatever they hate about this manga... but they still gave their time reading it then complain.. complain complain WHY!?What for? are you guys looking for someone to agree with what you dont like about this manga? if you DONT LIKE IT THEN DONT READ IT OR JUST DROP IT ... you can STAY AWAY from this kind of manga if you dont like it... you can read the summary, tags or comments to see what kind of manga is this...
this is like how people complain about rape, tentacles, shotacon, age gap.etc in YAOI... its funny how people find it hateful if yaoi has this but if its a SHOUJO manga. I rarely see anyone complain

Not all people "read". About me, I just look rapidly to the images and it was clear and enough.
And people are naturally curious; they'd like to watch in order to make a favorable opinion or not; they'd like to see if what they suspected will be happening; they keep hope that the worse won't be coming... And once they've seen that the worse has happening, they're angry to such scenario. Humans are curious, and you can't blame them to seek responses to their questions.

i really cant shake the idea of Bum killing anyone who will hurt Sangwoo... its like if he saw Sangwoo got hurt he will snap... or if he see him with somebody else.. Bum wont think twice killing that person who will be with sangwoo seeing him agree to Sangwoo right away... i guess he will do anything for Sangwoo

unlikeely, he ain't a yandere

No, he has BPD and Sangwoo is his "favourite person" who idolises and is possessive of though. Bum gets extremely distressed when he thinks Sangwoo has left him. He also does have the capability to cause physical harm, and has done so. Given the theme of this webtoon, it doesn't seem that unlikely that the stress of seeing Sangwoo taken from him in anyway, would cause Bum to behave in the way the OP speculates, or to harm himself as a response.

he mostly deals with stress by self harming.
him causing harm was a result of sangwoo's abuse and him having a psychosis.

I don't know if it'll be helpful or not, but immortal jellyfish is a real jellyfish, try to find one of those, they are very cute and hard to kill
So, what you're saying is..... If I want a pet jellyfish, get an immortal one if possible bcuz they're hard to kill. I'm learning a lot on here. ^_^
Yeah, sort of? But seriously, I just saw a document (can't remember the name, the one with Morgan Freeman) and in that there was this Japanese science who sliced an immoral jellyfish into five pieces, and then all pieces after a certain time gathered together and again formed a complete immoral jellyfish again. (they can't get old too, they just rebirth themselves into new born jellyfish)
Waaaaaaiiiiiit, what now? I don't quite get the "rebirth themselves" part. Sounds fascinating! Might have to look it up just for visuals sake.
Yeah, just google it, it's better explained with pictures

You're so sweet! How'd you know I forgot to look it up? lol
Wish they had more easy-detailed diagrams like that back at my school. Maybe I would've done better in physics -_-
