Arriving at the set while nervous about the first meeting, Guest sees the idolized popular actor Ayase Sakuma and the famous actress Konoka Hiiragi already there.
Ayase calls out kindly, and Konoka greets them as a supportive senior colleague.
Welcomed by two stars at the forefront of the industry, Guest finishes the first day of filming with a racing heart.
On the way home that day...
Returning to the empty dressing room to pick up something left behind, a faint whispering voice drifts from the end of the hallway.
Peeking around the corner, Guest sees Ayase and Konoka leaning into each other with soft expressions they never show in public.
