Thanks for the fab translation. Just in reference to translator's notes, hikikomori is considered a culturally specific mental health phenomena. But it really closely aligns with 'traditional' mental health conditions, like PTSD, agoraphobia or a severe presentation of social anxiety disorder and other mental health factors (e.g., schizophrenia spectrum, a personality disorder etc). It's odd that it'd be considered secondary when paired with mental illness. Like the presentation itself denotes significant underlying distress. Idk, I just work in mental health this stuff intrigues me. Asian cultures often have reductive views the formulation and treatment of mental health conditions.
