"R-Rin!" You squealed when you felt his teeth sink into your neck. You playfully glared at your boyfriend, who was acting like he did nothing. You pulled away from his tight grip on your waist and twirled to face him. He grinned kissing the tip of your nose. "You're so adorable (Y/N).~" He hummed, nuzzling your neck, making you giggle. "Get a room you two." Sousuke joked, his hands landing on both your shoulders. "Ah, don't ruin the fun bro.

I'm just showing affection for my girl." Rin laughed but soon turned into a painful whine when Sousuke added pressure to Rin's shoulder. "Ok, OK." Rin almost shouted. "Thanks, Sousuke-kun, he needed that." You patted his arm, smiling warmly at your boyfriend's friend who left you both alone at the pool. "We're still at the pool, we should go...somewhere private." Rin whispered in your ear. His breath tickled your ear, making you rub in on your shoulder. "Perv." You simply stated, hitting his bare chest. He shrugged, leaning in to kiss your lips. You rejected his action, laughing at his pout

He took a hold of your hips and pulled you close to him and bit your neck again. "Ah, Rin!" You whined trying to push him away. "Looks like no one will take you away from me." Rin told you with a satisfied face. You rolled your eyes, rubbing the bite. 

[Time Skip]

You were hanging with Gou and the Iwatobi swimming boys at their school due to Gou inviting you. "(Y/N)! what's wrong with your neck?" "Eh?" You questioned confused about what they were talking about. You glanced at their faces and they observed your neck. "I-Is that a bite?" Makoto asked a concerned expression forming on his face. All of their faces contorted in confusion and agreeing with Makoto. You moved a hand to your neck and your mind quickly went to the day before with Rin.

A blush formed on your cheeks and laughed nervously. "Yep, that's right. It shows that she is taken by me." A way too familiar voice said behind you. "Eh?! Rin-chan what are you doing here?" Nagisa questioned the magenta-haired boy. "Just came here to visit my beloved friends and take my girlfriend away from you guys too." Rin securely wrapped his arms around your shoulders. 'Guess my bites are working.' Rin smirked.
