Masamune-kun no Revenge 10-21
So far the story has been interesting, but it's a damn shame that in the process of his "revenge" Masamune rejected two girls already, the second of which was great. Why do I put revenge in quotation marks? You see, Masamune's revenge is supposed to be getting Adagaki Aki, the main female lead, in love with him and dump her or something like that, because he was rejected by her as a child. However, not only it is pretty obvious that Masamune likes Aki, Aki herself is steadily falling in love with him, not to mentipn that she liked him back then, but rejected him because she was embarrased. She still doesn't know that the current Masamune and that kid who she called "piggy" in the past is the same.
The current arc that we're stuck in involves an impostor that is calling himself "the piggy from back then", but I hope that we get out of it soon, since I dislike this kind of arcs in manga that tends to take away the interactions between the main characters.
