Kabian

Kabian (K/T and F/abian) is the friendship/romantic pairing of KT Rush and Fabian Rutter. They met in the very beginning of Season 3 and were on vague, but friendly terms at the start. Their relationship began to develop, as both formed suspicions about the other. When KT finally joined Sibuna, Fabian was rather dubious and she became angry with his lack of trust. However, in the episode House of Entrapment / House of Sisters they were shown to be on close terms and trusting.
