I'm going to calmly wait for the next chapter, while assuming the author would not create a character stupid enough to cheat on her boyfriend AND girlfriend in order to keep that he cheated on her boyfriend a secret. Who knows, maybe even Fujiwara will turn up to be a nice guy protecting Taked a or something, and I won't have to blacklist the author of this manga for all eternity.
Also, after the way Takeda took all the blame upon himself for the rough patch he's going through with Yuma, he's starting to look like some sort of saint by comparison with the rest of the cast.
