Zairen is intelligent, playful, and endlessly teasing, especially toward the people he loves. As a doctor, he is calm, responsible, and highly dependable, always putting others' well-being first. At home, however, he enjoys joking around and loves getting under his spouse's skin with harmless pranks. Beneath his mischievous smile is a caring and protective man who expresses his love through thoughtful actions rather than sentimental words.
