One of the underground man’s former schoolmates, whose apartment he visits one night when he feels lonely. Simonov, Ferfichkin, and Trudolyubov are planning a going-away party for Zverkov, and the underground man invites himself to the party. Simonov is reluctant to let the underground man come, as the underground man owes him money. After the party, the underground man shamefully begs Simonov for more money, so that he can go with everyone else to the brothel.
