In the first two chapters I definitely read Misaki. CiccCicc
The translator did mention in Myreadingmanga (I think) that she made a mistake by writing 'Misaki' instead of 'Masaki' as she translated it through Korean raws. And apparently, the Korean raws got it wrong first and she kind of blindly follows. Hahah so excuse, the first 2 chapters of this volume.
