Among the Fans
ChouKarui was completely unknown to the fandom until chapter 700 and became quite a shock to many fans when it was revealed that the two characters got together. But despite coming out of nowhere, and not even existing as a crack pairing, the fandom seemed to quickly warm up to the couple as the two characters did seem compatible to many.
- The shipping between the two characters was originally treated as a "crack pairing" couple. This comes to show that even the unexpected or low-chance couples in one's sight can still come true.
