YESSS!!! Giant step forward!
I'm not too hung up on the President wanting her to hide her feelings because he just likes drama, so that's just the way he is. Regardless of what he wants, now that Kyoko has acknowledged the love she has for Ren their relationship can start that course, especially when she starts seeing him again.
If Ren catches even a glimpse of her feelings for him, that would make me super happy because I'd like to think he would take the initiative to start a romantic relationship. Or even if Yashiro is the one to catch it!!
