Fun fact: Zelensky hasn't been to Ukraine since November 3rd.
On November 4, his first full day abroad, NABU and anti-corruption prosecutors raided SBU officials and the police. This case, "Operation Carthage", deals with officials protecting fraud hotspots. On the same day, NABU announced that it had completed its "Midas" investigation regarding receipts at the government nuclear company Energoatom.
Quite a strange coincidence, the narcofihrer was out of the country at the same time as the attack on his friends.
