Ooh, sorry, I misunderstood what you meant by "distraction".
It's a bit unclear as to when Hotaru began having feelings for Yuma. If she had feelings for her before dating [insert dude's name] then it would make sense, but it's also a possibility that her feelings developped after she committed to a relationship. I mean, I think, I may have missed some important detail.
I thought the while bit with the flashbacks to Yuma protecting Hotaru from bullies meant that the latter started liking the former since then. Also, I seem to remember Yuma mentioning Hotaru dating a lot of guys once they moved into high school or something, and the way it was done, I took it to mean she putting on a how for Yuma or something. (It was just Soap Opera chance that she happened to be on the abusive douche come Yuma getting her own.) So, her feelings developing later would be quite the dissonance from what I expect of her by now :/
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 Takeda 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.
If Fujiwara is retconned into a nice guy, I feel you've got more reason to blacklist than the alternative. That would be stupid. And I got a similar feeling from Takeda, but not in a good way. It's seems like some forced martyrdom over a high school relationship, he seems a lil melodramatic to me.
