has anyone else here read ‘the beast must die’ ??

Yes

i feel like that kinda bittersweet adapting ending

That is Similar to this one??

In the sense one of them is literally a psychopath, I feels it might be an ending where there is no ‘healing’ or like ‘all will be good from now!!’

I haven't read this one yet and i donno if i will read it. The beast must die was weirdly sweet sometimes? I donno what type of psycho vibe this one has. Don't want to traumatize myself too much

wait my brackets were for emphasis not to list another manhwa ahah
