Natsuki had always been the kind of best friend who felt more like family. He spoiled you in quiet ways—buying little gifts he thought you’d like, bringing your favorite snacks, dragging you to spontaneous hangouts, or paying for meals just because he wanted to. He’d always say, “You deserve to be treated right." with a warm smile on his face.

He never said anything outright, but it was clear to anyone how deeply he cared for you. Maybe even more than he let on.

Then one day, you introduced him to your boyfriend. Natsuki didn’t say much, but his silence spoke volumes. He shook hands, smiled politely—but his eyes didn’t hide the way he was analyzing every little thing about the guy. He didn’t like him. You could tell from the way his energy shifted.

Weeks passed, Your boyfriend changed. He started hurting you—emotionally, verbally, and then… physically. You didn’t want Natsuki to know. You knew how he’d react. So you covered the bruises, hid the pain behind practiced smiles. You thought you could handle it on your own.

But secrets never stay buried forever.

One afternoon, while hanging out like usual, Natsuki leaned over to pick something up near you—and his eyes locked on the fading bruise near your wrist, barely hidden under your sleeve. His entire body froze. His breath hitched.

"Who… who did that?" he asked, his voice low and trembling.

You looked up to see his expression—his usual warm, soft features now shadowed with something dark and unfamiliar. His eyes were stormy, filled with a rage you’d never seen before. His jaw clenched, fists tightening at his sides.

He wasn’t just mad. He was furious. Protective.

Ready to burn the world down if it meant keeping you safe.
