In the midst of our cohabitation, my relationship with my girlfriend had entered a phase of stagnation. We fought constantly, and I could feel that our breakup was drawing near. During her business trip for company training, I suddenly received a call. It was from my ex-girlfriend and childhood friend, Yuka Aoi. Back in high school, we both played on the basketball team aiming for the national tournament, but I grew jealous of Yuka's talent, and our bond gradually deteriorated. Eventually, we drifted apart and lost contact. But this time, her call came with the words, "I came to confirm my feelings." She suddenly kissed me, sending electric sensations coursing through my body. The vague emotions I'd been carrying all along were actually my feelings for Yuka. Realizing she was the one meant for me, we passionately devoured each other once again.
