Ahhhhhhhhh this is so cute!! And also so sad for poor Shirube, I felt for him when his parents didn't even care about the abuse! I feel like you did a good job of capturing Shirube here, his genius and general lack of emotions outside of vague irritation. But then that moment with Sunao! Where he actually seemed vulnerable and had feelings! They're seriously so cute, I hope Shirube holds onto Sunao's warm smile. :)
