Lol, RIP author not being able to deny their foot/feet fetish allegation XD
Miyagi and Sendai dancing around each other, both testing each other and testing the water for a possible level/next step to their relationship...Miyagi (Abandon money issues) and Sendai (Minor pride and self-respect)...They actually have brains, caution and self-control...Not like those videos online about people stupid enough to post their embarrassing moments like spazz out or screaming for clicks,clout and desire to validation.
Sendai extending a small olive branch by saying she was disappointment that they weren't in the same class when Miyagi lies and denies she wasn't disappointed that they were not in the same class (But Miyagi still hiding in her shell and trying to protect herself by not getting too close.)
A kiss scene between these two probably would take like another 15-20 chapters 'at least' from my guess??? I am just guess, seems to be slow-burn from what been reading and what I seen of the other comments' claims.
