"They're so cute together, aren't they?" Your ears perked up at the chatter of some other girls nearby. You turned your head to see what they were talking about. There was Daichi, your boyfriend, standing in the doorway of his classroom, chatting with Michimiya.

You couldn't help but feel a twinge of jealousy as you watched them. Daichi's broad smile and Michimiya's shy laughter made them look like a perfect pair. The other girls continued to gossip, their voices a mix of admiration and speculation.

"They've known each other since middle school," one of the girls said. "I bet they'll end up together."

Another girl nodded in agreement. "Yeah, they just look so natural with each other."

A knot tightened in your stomach. Daichi was yours, but the way he interacted with Michimiya made you uneasy. You knew they were just friends, but the casual intimacy they shared was hard to ignore.
