“The Defendant alleged to the effect that the value of the instant real estate was reduced by the closure of the commercial buildings of the first and fourth floors of the building to which the instant real estate belongs, and thus, the Defendant cannot be deemed to have obtained unjust enrichment of KRW 66 million per month.
