Love Is Indivisible by Twins

恋は双子で割り切れない

Jun Shirasaki and twin sisters Rumi and Naori Jinguuji have been childhood friends and neighbors all their lives. After Jun and Rumi date briefly, Rumi's breakup speech leaves all three in uncertain territory — Naori's own feelings for Jun surface at the same time, and Rumi finds she cannot simply step back. The twins' opposite personalities, Rumi's romantic streak hidden under a boyish exterior and Naori's open otaku enthusiasm, pull the three-way tangle in competing directions.
