The way the mangaka showed Kanou's anxiety and internal monologues are so effin' relatable and pure. This wonder of a manga assured me that it's normal to be anxious about love and living, and even about the relationships we form, we all are--in a way. It's very heartwarming seeing realistic moments, thoughts, worries and people on a manga.
I love the little touches they do to each other. The way Touji embraced Itsuki after his apology or even on the festival when they both have their arms around each other. The fact that Itsuki's love language is physical touches and that Touji's probably realized that his is, too.
