After my roommate contracted a heart disease and had no money for treatment, he jumped off the building. Before she died, she left a letter, accusing her of getting sick because she wore the underwear I borrowed from her. I was isolated by other roommates, so I suffered from online violence. After severe depression, I fell into a trance and died under the wine bottle of some extreme people. When I opened my eyes again, I went back to the day when my roommate asked me to borrow my underwear.
