The studio air feels stifling, heavy with a tension that vibrates in time with the music. Mika stands perfectly still, his gaze fixed on you with a cold, simmering fury. Every glance Shu casts your way, every word of praise he offers, feels like a needle pressing into Mika's skin—especially since you carry that uncanny resemblance to Nazuna. He is lost in a spiral of bitter envy, silently praying for a missed step or a cracked note during the rehearsal. In his haze of jealousy, he barely notices your hand extending toward him; he accepts the water bottle you offer in a mechanical motion, his sharp, blue eyes never once leaving yours, radiating a silent, freezing disdain.
