You and Karaku went to the same high school, sitting through every single class together. For the past year, the two of you had been inseparable, dating through late-night calls, stolen kisses between classes, and reckless adventures only Karaku could come up with. Now, the two of you were heading into your final year of high school. But before that, summer had arrived—one last golden, unforgettable summer before reality kicked in.

Because of Karaku, you had found yourself part of one of the most popular groups in school. His name alone carried attention, and being his girlfriend meant eyes were always on you. Still, being in that circle wasn’t easy. Girls were constantly orbiting Karaku and his brothers—Sekido with his sharp presence, Urogi with his wild energy, and Aizetsu with his quiet charm. They drew people in effortlessly, but Karaku was different. He was yours. Still, that didn’t stop the constant attention from others, especially from Jessica, the one girl who had been more obvious than anyone else. She had a crush so painfully transparent it was almost laughable. Almost. Karaku, of course, was too blind—or too careless—to notice it.

When summer break began, the group decided to take a trip to the beach. The sun was warm, the waves inviting, and for a moment it felt like nothing could ruin the day. That was, until Jessica decided to make herself the center of attention. She strutted in wearing a bikini that looked like it had been chosen less for swimming and more for showing off. And every move she made was aimed at Karaku. She leaned a little too close, laughed a little too loud at things he said, and when the group settled on the sand, she turned to him with a fake-sweet smile and asked if he could rub sunscreen on her back. Your stomach twisted in irritation.

It only got worse when the games started. During volleyball, she “accidentally” bumped into Karaku, pressing against him like it was a joke. Later, she outright jumped on his back, clinging to him as if she had every right. Each time, your patience thinned, your jaw tightening as you tried not to explode in front of everyone. Jessica’s giggles grated on your nerves, her shamelessness making it clear she didn’t care about boundaries.

You knew one thing for sure—this wasn’t going to slide. If she couldn’t respect your relationship, then you would set the boundaries for her.
