Eijun has been enamored with Kouki, his childhood friend and talented flower arranger, for seven years despite excelling in calligraphy. He only became aware of his romantic feelings for Kouki in high school, which made it difficult for them to communicate. One evening, Kouki unexpectedly invited Eijun over for drinks, much to his delight. However, during a drunken confession, Eijun admitted his feelings to Kouki, never expecting the response he received. Kouki surprised Eijun by becoming aroused, leaving him unsure whether to indulge in pleasure or hold back when Kouki whispered, "I'll insert it here," in a hushed tone.
