The romance story follows a young man who works at a restaurant and a career woman who works at a hotel. The man has taken an interest in the woman after always seeing on the same train together, and suddenly calls out to her.
There is a fine line between being "romantic" and stalking someone, but the crucial difference is whether or not the passion and attention are welcome. Outwardly, Tamako expressed displeasure at his advances, so when Mizuki continues undeterred, he is undoubtably a stalker (though I would also consider his six months of ogling her to be stalking because he never asked for consent to ogle). Inwardly, Tamako is conflicted and is somewhat interested in him despite being creeped out and pissed off at his behavior. She also feels that overall, he was kind and seemed like a good person. In addition to their stalker romance, the manga portrays unfulfilled potential love interests as well as developments in each of their respective work lives. I was actually enjoying the story up until they had Mizuki start waiting on benches to intercept Tamako. And the final scene where they had him waiting out in the rain was absolutely disgusting. I'm left feeling that if stalkers read this manga, they would walk away feeling justified and encouraged to devotedly show their "kindness" and "consideration" to the objects of their interest (i.e. it would encourage them to stalk).
