I love me a good academic rivals-to-lovers trope! I like Kurihara! I expected him to be more reserved, shy, and submissive, but he was actually really cute when he was upfront about how he felt. He didn't beat around the bush. I also love how Kawase stood up for himself when Kurihara insulted him at the library. I just love how natural the pacing of the plot is despite it being so short.
