Oono is unable to properly do his uniform check job because his adoration of Takeuchi distracts him, and Takeuchi mistakes this for Oono hating him and is sad at the idea of being disliked by the model student. Thus, Takeuchi is relieved and willing to reciprocate when he finds out that it isn’t hate but instead love that makes Oono so very awkward around Takeuchi.
I love this manga! It tells the story of two boys who despite being opposites - one is the head of the discipline committee and the other looks like a delinquent - develop feelings for each other. The mangaka does a great job creating a distinct look and personality for each of the characters, including the side characters which I personally find kind of rare in bl manga. The story has a sweet first-love kind of feel to it with no unnecessary drama. A super-cute school love story!
