Going back and reading, the MC showed signs of being suicidal from the start. He was always edging close to wanting to die. Everything match up for suicide to be here, lets just hope they can actually end the story properly.
i can kinda agree, that was the reason i got interested when the manga took this "twist", it sort of matched together somewhat nicely... my issue is more like i can't take them seriously.
Having a teenager explain that they built a small but surprisingly efficient information organization by... helping out other teenagers in hard circumstances... its simply ridiculous, plus the author setting it up like shes badass by doing that is funny.
Then we have another teenager but this ones (comically) mentally unstable to say the least and shes expected to help out the suicidal guy... i almost laughed when she got angry because "wanting to die" was mcs actual first place XD.
Helping out someone with suicidal thoughts/intent is awfully hard already, putting these teenagers as if they could handle it or as if they have any hope at it is annoying.
I mean im assuming mc won't succeed at suiciding because this is a shounen manga, if he succeeds ig what ive just said would become the "message" of the manga, altho feels like that would be a stretch.
