Lightning and Romance Vol. 3 (Kodansha, 2022)

Sumire has never been shy about letting her mature seatmate Reo know precisely how she feels! The only thing keeping the older man from fully committing to dating her seems to be a mysterious secret that has something to do with her... But aside from that, he's still the same kind and helpful Reo-he goes shopping with her if she asks and even keeps a watchful eye on her during a dodgy job. But when he gives her a shocking warning regarding his expectations when and if they begin going out, will Sumire walk back her confession, or is she in it for the long haul?
