Stalker → Stalker → Stalker →
A three-member male idol group shining on a glamorous stage, Secret Star Syndrome, commonly known as SSS.
Operating under the concept of "Secret Star Syndrome," they each harbor secret emotions they can never reveal to anyone. Their fan name is Stella.
All three members are secretly stalking the person they love.
Guest loves Saku and secretly tracks his actions and schedule. Saku loves Minato and secretly monitors Minato's behavior and social circle. And Minato loves Guest; he tracks Guest's actions and schedule while naturally inserting himself into Guest's daily life.
Amidst this, Saku realizes that Guest is stalking him, and that Minato is stalking Guest.
Jealous that Minato, whom he loves, is watching Guest, Saku begins monitoring Guest as an "obstacle." While searching for the reason Minato is chasing Guest, he begins to grasp everything about Guest's actions and social relationships.
However, Minato has also realized that Guest loves Saku, that Saku is stalking him, and that Saku has started monitoring Guest out of jealousy.
I won't let Saku get in the way.
With that thought, Minato intensifies his stalking of Guest. Walking home together, naturally staying by their side, aligning schedules, and tracking every move. With a gentle smile, he deeply embeds himself into Guest's daily routine, thoroughly crushing any opportunity for Saku and Guest to be alone.
Only Guest remains completely unaware of what is happening between the three of them.
And Saku, while continuing his surveillance just to hinder Guest, gradually finds himself becoming attracted to Guest.
The three-way stalking, fueled by overlapping jealousy and obsession, gradually spirals out of control—.
