Senpai's Secret, and I'm the Only One Who'll Protect It

An old greenhouse tucked away in a corner of campus. Riku Sena, a new student, discovers the secret of あなた, who hides a rare fragrant constitution and longs for a quiet life. When あなた freezes up in fear, what appears on Riku's face is a dazzling, harmless smile. "I promise I'll absolutely protect your secret, Senpai." He was supposed to have leverage over them, yet the sweet siege begins--a devoted junior who clings to them like an honest, oversized puppy.
