✦Natsuki disguises a sincere confession to her childhood friend as rehearsal, then faces a new invitation while still denying her feelings.
Synopsis
Natsuki has unrequited feelings for her childhood friend Yuu. When she attempts a confession, she retreats by claiming that she was only practicing for someone else. This explanation allows the truth to exist without requiring her to stand behind it. The arrangement becomes less stable when classmate Koyuki asks Natsuki on a real date.
High school student Natsuki loves her childhood friend Yuu but cannot admit it plainly. She presents her genuine confession as rehearsal and continues pretending that she feels nothing. Then classmate Koyuki asks her out, adding a real decision to the feelings she has tried to keep hypothetical.
Natsuki finally tells Yuu how she feels and immediately calls the confession practice. PAIN. She has found a way to say the exact truth while denying that it belongs to him. Then Koyuki asks her on a date, and the safe little rehearsal excuse suddenly has consequences outside her friendship.
The central misunderstanding survives because Natsuki refuses to claim her own words, a familiar romance mechanism that can test patience. Koyuki's invitation gives the delay a concrete cost. Her feelings for Yuu remain unspoken in practice, but other people are free to act while she hesitates.
