I mean, what did he anticipate? He intervened when she was on the brink of jumping off her apartment balcony, demonstrating genuine care for her well-being. She writes to him daily, relying on him as her support system. If he abruptly declares he's cutting off direct involvement to adhere to the socially accepted distance between a fan and their idol, it's only natural that she'd be upset. After all, he played a pivotal role in saving her life, and some responsibility should be acknowledged.

me ish getting red flag vibes

I can fix her

FUCK!!!!! I knew it, it's such a common trope in this kind of story about "the broken former idol".
Here is my guess The lonely girl who want to be loved. Decided she gonna be an idol so she will be loved by a lot of people. But she's not that popular compared to the other members of her idol group. Also in Japan the unwritten golden rules for idol is that they can't have a lover. So she's just become more and more lonely. Until maybe her staff, or producer, or maybe even some male idol she knew interested in her and then they got in to a forbidden relationship. She then found her "happiness" for a moment, until everything start to go downhill. Maybe she got cheated, or she was the side girls, or maybe her sex tape got revealed. So her agency decided to fired her. She got depressed, started committing self harm, changed her look completely, etc etc. till we come to the current situation.

not healthy at all someone will end up dead

Someone needs to slip this lad a copy of Boys Abyss.

oof, a menhera, thread carefully bro and don't get attached, she likes the attention you're giving her, not you.

Ah... he got glued with crazy
Let's hope he can out crazy her craziness

i know i shouldn't be because of the themes this manga covers, but seeing her wrist surprised me somehow

Oh... Her arm in the last pannel....
Ok hear me out, imma put my tinfoil hat on for this one.
I'm guessing her ex realised she's a yandere and dumped her which worsen her mental health which lead to her quitting the band.
For the very least I think she had a very bad experience in her last relationship.

Oh shit her arm.

Smt is off abt her i can sense it
