Let's Kiss in Secret Tomorrow Vol. 2 (Kodansha, 2020)

Saya and Yuto were best friends before they decided to start dating at the end of junior high. They thought they'd be glued at the hip for the next three years in high school… Until Yuto shows up at the entrance ceremony with a brand-new look! Saya shuts down when the other girls show up asking questions, hiding the fact that he's already taken. In order to shake them off her trail, she reinvents herself on the spot, too… as a total nerd! As Saya frets over the growing distance between her and Yuto, that's when a new threat appears! My newly-hot boyfriend, and newly-nerdified me. The secret love story continues in volume 2!
