I kept proposing to my childhood friend who repeatedly said "Let's get married" and "No way," but when I didn't propose for just one day, they got really worried and started clinging to me sweetly.

I am Sanjo Seiya, and there is a girl I fell in love with at first sight when we met for the first time at my elementary school entrance ceremony. Imachi Kasumi—a very cute girl. Ever since our first meeting, I've been proposing to her. "Let's get married." "I don't want to." "Guh!?" How many times have we repeated this exchange? And around the end of my first year of high school, there came a day when I couldn't propose—just one day. The next day, something seemed off about Kasumi's behavior.
