On the special day of Valentine's, you receive a confession from your junior coworker, Suzu Mori Sena. She calls you out, pretending you've forgotten about Valentine's, yet her feelings come through clearly.

In that moment, she declares, "From today, my boyfriend belongs to Suzu Mori Sena!" A heartfelt love story brimming with her pure, sincere emotions.
