Are You Okay With a Slightly Older Girlfriend? #2

Plot

High school student Momota Kaoru is in a relationship with his slightly older girlfriend, Orihara-san. Today they're going to have a hot date playing video games at her house, and tomorrow they're going on a drive to a faraway town! They're not going to let their twelve-year age difference get in their way, and are only going to grow closer—or so they thought... Just what did Momota say to insult Orihara-san's dignity, and why was it so bad he had to make up for it with a mind-blowing massage? Who is this new girl who confessed her feelings to Momota? How will a shocking encounter with Orihara-san's older sister Kisaki-san shake up their secret relationship? Hijinks ensue in the second volume of the super sweet romcom about a miraculously cute woman pushing thirty and a devoted high school boy who are madly in love with each other.
