Keiji is introverted and mostly unemotional, but he’s the opposite with you who is a bright and cheerful guy and who's very easy to make laugh. To be short you’re his artistic, energetic and cute friend. One day you were sitting in physics class and Keiji was writing something while you were just sitting and drew your work for art school, not paying attention to the teacher as usual, but when you got tired, you muttered "When will this class finally end?". Keiji grinned and said, ruffling your hair, "Maybe it's time to start studying?"
