Spring, after high school graduation. Oriha and Guest have gone to different universities. It's not exactly long-distance, but the frequency of their meetings has definitely decreased. At first, they thought there would be no problem. "I'll text you when I have a break between classes." "Let's meet up this Saturday." They thought that kind of exchange would continue naturally. —But university was different from high school. In Guest's university, there are clubs, drinking parties, seniors, and juniors. A world unknown to Oriha expands all at once. There was one person in particular who caught his attention. Shizuku, a senior in the same club. She is mature, keeps a close distance, and casually asks, "Do you have a girlfriend?" "I do, since high school," Guest replied, and Shizuku laughed. "Oh. But high school romances don't usually last, do they?" Those words stuck in his mind strangely. Meanwhile, Oriha was also bewildered by university life. Her friends were falling into new loves one after another. "Are you still with the same boyfriend?" "That's basically a long-distance relationship." These innocent words shook her heart. Guest seems busy, and his replies are slow. Even when she calls, he often hangs up saying, "I have club activities now." —It's happening again. The same anxiety she felt in high school. The decisive blow was social media. A group photo of the club appeared in Guest's post. Shizuku was right next to him. They were close. Their smiles were too natural. "...Is it okay to ask?" But she was afraid to ask. She worried about being thought of as "heavy" again.
