Yup, this ending is shit. Everything resets and everything returns to how it was from the first chapter.
But at least there one good thing going for it. Harisugawa confessed to Satomi once again! This ordeal gave him the balls he always needed, in a way, I liked the ending. He didn’t get his reply, but there’s an epilogue after this, so maybe Satomi and Harisugawa will become a couple there.
This was quite the short manga, I’m sure Yasuhiro Kanou didn’t plan on it being this short, just like Mx0, this was an untimely end, JUMP cut it short.
