Summary
Before the petrification event that changes the world forever, Valentine’s Day arrives at Ishigami Senku’s high school. Six months into dating the science-obsessed genius, (Y/N)—a figure skater with a sharp mind for biology and chemistry—decides to leave him a handwritten note in his locker instead of interrupting his research. It’s an invitation to dinner, a quiet confession of effort, and a hopeful risk.
He never sees it.
Lost in rocket designs and strange petrified birds, Senku skips his locker entirely. He’s affectionate but distracted, and when his only text at the end of the day says not to wait up, (Y/N)’s heart sinks. She understands his tunnel vision—but that doesn’t stop it from hurting.
Instead of letting the day fall apart, she creates her own Valentine’s celebration: pink, heart-filled ramen made with careful food chemistry, music blasting as she dances through disappointment. Just as she sits down alone, the doorbell rings.
Senku, breathless and apologetic in his own awkward way, finally shows up—ready to learn, to listen, and to share a Valentine’s night that’s unconventional, nerdy, and uniquely theirs.

Summary
In a shared college dorm, a late-night study spiral pushes you past exhaustion and straight into burnout.
Senku notices—of course he does. With ruthless logic and infuriating affection, he stages an intervention: confiscated notes, enforced hydration, real food, and a break that you refuse to admit they need.
