I think in some chapter it was a flashback?
Yep but even the first raw chapter, which is Vol 5 Chp 3, I thought Hiromu was a different character at first. Then saw Masaki and thought maybe this was a different work by the same author and was mistakenly uploaded here. But then Hikari was there and I got confused. I became reassured when the other characters were shown. I had to reread the pages before the flashback just to be sure hahaha
I reread and reviewed the older chapters' art and I think the art style did change. I assume the newly uploaded raws are new releases so a style change did likely happen. The characters in the new raws look slightly sharper, a bit more angular than before and somewhat thinner. Well, change is inevitable and can happen to artists. I just have to get used to the new art.
I just saw the newly uploaded raws. Is it just me or did the art style change??? I didn't recognize Masaki and Hiromu at first and the other characters looked different to me as well. I was so confused for a moment. Thankfully Hikari's cute little pouty face when he says "bu~" is still the same hahaha
