This manga is nothing unique, it's an insta-love story about a high school girl crushing on a young adult who works as a train station attendant. He's obsessed with trains and really doesn't have good social skills (read: he's a bit of a dick outside of work), but he's great at faking it when providing customer service. After confessing her love the female MC takes his attitude in stride announcing she finds his ability to fake it all day at work to be a sign of strength. It's a laugh.
Nothing ground breaking, and I don't get the same big laughs from this as I do from Lovesick Ellie or Takane and Hana. If you take this series for what it is, fluffy shoujo cuteness, it's a good wind down manga available on Mangamo and Amazon.
