NXT_MARVEL

Isagi Kawaguchi was just an ordinary guy — until he woke up in the world of Blooming Hearts, his favorite school-life romance anime. But there’s a catch: he’s reincarnated as an extra. A side character so insignificant, his entire screen time in the anime was five seconds.
But Isagi refuses to stay a background character. Fueled by the regrets of his past life — where he wasted his youth buried in books — he’s determined to live life to the fullest this time. And his biggest goal? Winning the heart of May Minase, the sweet and talented girl who captured his heart when he watched the show.
There’s just one problem. Or maybe several.
Rin Kazuki, the perfect protagonist — handsome, brilliant, athletic, and already well on his way to building his dream harem. And May? She’s supposed to fall for Rin.
But Isagi isn’t backing down. From joining clubs to standing out in class, Isagi is ready to fight his way into May’s heart — even if it means taking on the ultimate protagonist himself.
Let the battle for love (and survival) begin!

My Battle for Love in a World Where I’m Just an Extra

he evening sky shimmered with soft shades of gold and crimson, casting a warm glow over the dormitory grounds. The gentle breeze carried the scent of blooming flowers, and there was a calmness in the air that felt almost magical. May and Isagi walked side by side, their steps syncing naturally as they made their way toward the nearby park.

May stretched her arms with a contented sigh. "This weather's perfect, isn't it?"

Isagi glanced at her, his heart giving a familiar flutter as the light danced across her face. "Yeah, it really is."

They settled on a bench beneath a cherry blossom tree, the rustling leaves filling the quiet space between them. May swung her feet slightly, her gaze wandering across the tranquil scenery. "Everything feels so peaceful now… after the festival, after everything. It's like a dream."

Isagi nodded, his fingers tracing the edge of the bench as his thoughts swirled — the firework festival, their shared moments, and the feelings he still hadn't put into words. He wanted to tell her, but the words always stuck in his throat.

"Isagi?" May's gentle voice broke through his thoughts. She tilted her head, her warm brown eyes filled with quiet concern. "You've been kind of quiet. Is something on your mind?"

He hesitated, his pulse quickening. "I… I'm okay. Just thinking about some things."

Before she could press him further, a sudden breeze sent a flurry of cherry blossom petals dancing around them. May giggled, reaching out to catch one. "It's so pretty! It feels like something right out of a fairytale."

As Isagi watched her laugh, the urge to tell her how much she meant to him grew stronger. But before he could speak, his phone buzzed.

"Of course," he muttered, checking the screen. A message from Kaito popped up: "Hey, you two lovebirds wanna grab dinner? Akari's already picking a spot."

May peeked over his shoulder with a playful grin. "Looks like we're being summoned. Shall we?"

He smiled, slipping the phone back into his pocket. "Let's go."

As they walked away, their hands brushed — a fleeting touch, but enough to send a spark through him. And in that moment, Isagi knew one thing for sure: he couldn't keep his feelings hidden forever.

The time to confess was approaching… and their love story was only just beginning.
