I feel a bit disappointed by the end of the first season and I'm not too motivated to read the second one, tell me, is it worth it? Could someone make me a short summary of what happens in the second season please? Thank you soooo much in advance <3

Eeeh, I'd say no. Second season is an entirely different couple. I was going to try to summarize it, but the plot is so fucked it's hard to do it succinctly. First season was pretty good, but they feel like very different stories. Below is a super short, very spoilery TLDR, though.

If I had to put a TLDR on it: one character has DID, is obsessed with MC, eventually kidnaps him, his alter personality takes over, the devil steals his soul, the alter pretends to have amnesia because he's just as fucked up as the main personality and that was the only way MC would stay by his side.

I actually like this second season more, since the first one felt like the ending was rushed.
This second season revolves around the book and explains sort of how it works, but it’s a different couple.
You should read it, it’s really interesting.
Basically it shows Mc, who gets tangled between his love interest and his twin, but it has many plot twists and manipulation so beware

But a good crazy, the kind of craziness that leaves you with so many feelings.
Everything was good in this story, be it the drawings, the characters or their reactions, everything was crazily, amazingly gorgeous and fascinating.
It is underrated, I saw many people mentionning Killing stalking but what I read of it didn't give me nearly as many feelings (is that sentence understandable I wonder x) ) as Interview with a murderer did.
It is a master piece, a chef d'oeuvre.

I wasn't expecting anything (ah seeing the lists it was in I thought it would be a bit morehardcore) and thank god I wasn't because I didn't get any feeling reading this. Only annoyance, maybe, the story was so flat and nonsensical, the nsfw parts weren't even sexy, the stockholm syndrom was just too fast and nonsensical... It clearly wasn't the worst I've read, but even if I am never searching for realism in yaoi (as one shouldn't x) ) I found it too unrealistic to be readable. I shouldn't even write this much on such a short and fast-paced thing, good night peeps <3
I really enjoy ready S&M (partly because I don't embarass myself with the customs of S&M relationships, like I don't seek realism in yaoi) but the crazy Hibiki story had nothing to do with that.
He was just plain cruel and, although I hate blaming it on the victim, I have to admit I was really annoyed by the seme's reactions to the situations. But well, Hibiki is the worst and seeing their relationship was pretty painful, not past (not even re-marriage stories) can justify his awful attitude toward his boyfriend, who he clearly, undoubtedly repetitively raped.
