Placebo has 2 vers tho—short and long. Haven't you read the latter?

Placebo: Let's Play (long ver) https://www.mangago.me/read-manga/placebo_let_s_play/
I've read it, but if the short story was an extra strong espresso, the long story is what you get when you take those same coffee bean grounds that were used to make the espresso, throw away half of it and use the rest to make 20 litres of regular coffee.
It's weak, so I like to pretend it doesn't exist and daydream about one day getting proper sequel that is just as unhinged as the short story, but hopefully even more

When I saw people complaining that this story was worse than Placebo I thought they meant in a filthy way and I got really excited because the short story version of Placebo is one of my all time favourites.
It's too bad they never made a longer version, I hope they will one day and that it's at least as unhinged as the short story.
Sadly I was deeply mistaken.
The art is kinda pretty and that size difference is unggggg, but the plot and execution are just bad.
Placebo had sex in front of hypnotised parents, this one has attempted murder in front of hypnotised parents.
24 chapters in which nothing is explained and a 4 page flashback at the end with a partial reveal of how it began...
Want to know if little brother is a ghost, a demon or something else? Sucks to be you
Want to know the reason why big brother was sometimes a seemingly enthusiastic participant and other times couldn't remember anything he'd done with lil bro? Fuck you, that's why
Wonder what powers lil bro has and how they work exactly? Accept the fact that you're going to live the rest of your life without ever finding out.
When short story Placebo ended I was desperate for more
When this story ended I was annoyed that the author hadn't used those 24 chapters better
It's definitely worse than Placebo
