Hanamaru's manga / #Stalker(1)

Summary from MyAnimeList.net Ore no Kanojo ga Stalker na Ken (オレの彼女がストーカーな件) Hoshino Haruto gives off a "bad boy" vibe: he is cool, calm and collected, which makes all the girls in school swoon for him. Yet in truth, his cold facade is just a mask for a 16-year-old virgin's nervousness and naivety. Just as he promises himself not to fall for a carnivorous girl again, his life is turned upside down by a weird stalker, Seo Minamo, who drools over her fantasies of him. What will happen now that he agrees to go out with her?
