What concerns does Ukraine have about a potential ceasefire negotiated by the United States?

Ukraine fears that a U.S.-brokered ceasefire could become problematic if America becomes increasingly disinterested and favors Moscow in the negotiations. The correspondent notes that such a scenario could be "very messy and uncertain for Ukraine" if the U.S. shifts its priorities. Despite Ukraine's desire for peace, there's concern that any agreement might not represent the end that Ukrainians actually want. The worry is that American interests could override Ukrainian needs, potentially creating an unstable situation that doesn't address Ukraine's security concerns or territorial integrity.
