I really love how it built up Chiho learning to take Midorikawa's feelings and potential as a partner seriously because she was the one who was there for her in the way she needed during a moment that was way more serious than I would have expected. It's a neat way to follow how she was so oblivious that she outright didn't understand Midorikawa's feelings when she outright confessed, but she came to understand them now after she decided not to confess and to just be there for her friend. I'm really happy with that arc.
Best girl truly won. Although it ended up not even being a real harem thing, haha.
Buuuut vice president is still too enamored to break out from the president's carrot-and-stick manipulation thing. That's a bittersweet end to it. Ouch.
