Kei, a socially awkward student, maintains a secret online romance with a girl named Eve, whom he suspects is actually his classmate Midori. While Midori is deeply in love with his online persona, "AW," she remains oblivious to his true identity in real life. When a planned trip to a summer festival is derailed by Midori's selfless attempt to play matchmaker between Kei and his childhood friend Miki, Kei finds himself caught between his digital fantasies and a complicated real-world connection.
After Miki returns to school, she challenges Kei to help the emotionally distant Midori overcome her traumatic past as a condition for forgiveness. While navigating a fake relationship with Eri and managing his secret online persona, Kei and Midori discover a deep connection rooted in their shared experiences with abusive fathers. Their bond culminates in a passionate encounter, though Midori reveals via email that she must move away after the summer vacation.
