My friend has had psychopathic thoughts for years now & I've always been meaning to help them by taking psychology when I graduate secondary school next year. But recently, they've been telling me that they don't care about anything anymore & that person had been seriously considering murder and kidnapping - & I could tell that they hadn't been kidding.

Suddenly, I had this thought of becoming an informant like Orihara Izaya (from the anime 'Durarara!!') and getting myself acquainted with the criminal underground, so that if my friend ever did go off the deep end, I would be able to help them.

The second thought is nothing more than a passing whim, but the short moment that I had seriously considered it would never leave me, because I care about my friend too much to let them attempt something so dangerous alone.

Tell me what should I do?
