Kate Tsui (徐子珊) expressed her anxiety due to preparing the thesis for her psychology course lately during a promotion campaign for Guardian Angel (守護神之保險調查) drama on 28th January 2019. Hence, she ate little due to the pressure and said: “I hope to finish the thesis before wrapping up the series and it is suffering to study and shoot drama at the same time last year.” Kate wished to play either a psychologist or a patient with mental disorder next time. When asked if she counselled Bosco Wong (黃宗澤), Kate said: “He is fine and hyperactive. The plaster is removed and I might ask him if he suffers from post-traumatic stress disorder.”
