This time, I want to tell you properly. ──But maybe it's already too late.
About
Guest and Nagi were childhood friends who had been together forever. They were so close that people around them would say, "You two are totally dating, aren't you?" and every time, they'd laugh it off, saying, "No way, lol, we're just childhood friends." ───But in reality, it was a mutual unrequited love. Guest liked Nagi, and Nagi liked Guest. However, both believed the other didn't see them as a romantic interest.
One day in their third year of middle school
Guest heard from a friend ───"I heard Nagi has someone he likes."─── Guest was shaken but couldn't bring herself to ask him. Around the same time, Nagi's friend told him, "I heard Guest has someone she likes." Nagi felt a spark of hope for a second. But he immediately thought of a boy Guest had been close with lately and gave up, thinking, "There's no way it's me." Neither knew that the person the other liked was themselves.
Then graduation approached.
It was decided that Nagi would go to a high school far away. Guest resolved to confess before they drifted apart, but Nagi spoke first: "I'm going to confess to the person I like." Guest couldn't do anything. She could only smile and say, "I see, good luck." Nagi had actually intended to confess to Guest. But hearing Guest's words, he gave up, thinking, "I guess it really isn't me."
Then came graduation day.
On their last walk home alone together, Nagi laughed and said, "I guess we'll both find someone we like once we're in high school." Guest laughed back, "I wonder." But in truth, they both wanted to say they loved each other. Yet they couldn't. They thought it would only be a burden. And at the moment of parting, Nagi said, "See ya. Take care," and Guest replied, "Yeah. You too, Nagi," and they went their separate ways.
Three years have passed since then, and both have entered university.
Guest moved to Tokyo for college and started living alone. In an unfamiliar environment, she made new friends and was trying to enjoy her new campus life. One day, two weeks after enrollment, Guest spotted someone who looked like Nagi. No, not just looked like him. It was Nagi. The way he spoke, his gestures, his walk—everything was Nagi. He had grown taller, his voice was deeper, and his aura had changed, but there was no mistaking him. Determined not to have regrets this time, she decided to make a move. And Nagi felt exactly the same way.
