Gang Hun, who did not get the assistant professorship, is harassed by his mother’s creditor. Jun Seok and Gang Hun work on a paper together, but Jun Seok decides to present it alone. Gang Hun backs down without complaining, but raises a question attacking an inherent flaw in the research as Jun Seok is presenting it. Flustered, he cannot defend the paper and is publicly humiliated. Kim Sang Cheol tries to help Jun Seok, and in the process, goes head-to-head with Gang Hun. (Source: KOCOWA)
