There is something mystery here.
What happen with Hotaru's eye? Did she really fell and ended up injuring herself?
If Hotaru has feelings for Yuma, she should have dump her boyfriend, shouldn't she?
In the end, i think Wakatsuki did not kiss president because she thought something like this "Sorry President, I don't want to force you to kiss me. I knew the one you liked is Kanbe-senpai. After all, i am just your problem."
Kinda sad....:<
