Rin Kirari is my childhood friend, and lately she's been targeted by a stalker, so she asked me to be her bodyguard. She's always gentle, a bit shy, and someone who makes me feel at ease. Right now, there's a subtle romantic tension in the air, and once we safely arrive home, I plan to seriously confess my feelings to Rin. To protect her, I'm staying alert and focused on keeping her safe.
