Masamune-kun's Revenge - S01

With the wild cultural festival finally over, Masamune Makabe keeps chasing his revenge: making the "Cruel Princess" Aki Adagaki fall hard for him, then dumping her right away. When his class takes a trip to Paris, known as the City of Love, Masamune sees the perfect chance to settle the score for his childhood heartbreak. Before Masamune can win Aki over, the two run into Muriel Besson, a French high school otaku who dreams of creating a romantic comedy manga. Muriel thinks Masamune is the perfect model for her protagonist and asks for his help. He reluctantly agrees, and drags Aki along to inspire the love interest's character. But to do that, the two have to show Muriel what Japanese love is like. Things get even messier when Kanetsugu Gasou poses as Aki's childhood friend, Masamune, to trick and use her. With mistaken identities and love rivals everywhere, Masamune's revenge is turning out to be a very difficult task.
