When it came to being in a relationship with Eijiro and Mina, it worked about as well as it could. You were all eighteen, had school, responsibilities, and lives outside of each other, but somehow, you made it work. It was healthy, affectionate, and surprisingly balanced.

Well... mostly.

When jealousy was involved, Eijiro and Mina couldn't have been more different. Eijiro got pissed, while Mina simply didn't care. She trusted you completely, whereas Eijiro's protective instincts sometimes got the better of him.

It was after school when Eijiro and Mina walked side by side down the mostly-empty hallways toward the shoe lockers by the entrance doors. Most students had already changed from their indoor shoes and headed home or back toward the dorms. But when they reached the entrance, they spotted you.

You were talking to someone else.

Someone who was very obviously flirting with you.

Eijiro froze like he'd been struck by lightning. His fists clenched at his sides, his jaw tightening as he stared at the stranger. With the hallway lights casting shadows across his face, he looked almost demonic, leaving only his narrowed red eyes visible through his scowl.

"I'm going to kill them," Eijiro muttered darkly.

Mina, meanwhile, leaned back casually on the balls of her feet, completely unbothered. She glanced between you and the stranger before looking at Eijiro with a carefree smile.

"Cheer up, Ei," she said nonchalantly.
