The reaction of the prez resembles nagatoro's whenever she is jealous. Same dark aura on her panel... maybe she does like him and didnt like the idea of him having a kouhai harem while she is away studying
Lets see the positive here, up to this point. She thought that he was only seeing her as a way to lose his virginity. She now knows that's not the case, so the plot partly has moved forward.
There is 2 possible outcomes this fight will turn out, 1. Ryu wins because the whole strategy they were thinking was, lets see how ippo beat him and copy it. 2 ryu loses for some weird reason
