Love Is Indivisible by Twins

Rumi and Naori are twins but have nothing in common, except their feelings for Jun, their next-door neighbor.

After dumping Jun, Rumi makes another request of him, one that he couldn't have seen coming.

Jun, Naori, and Rumi have to come to terms with their new dynamic. Jun goes to Toyoshige for advice.

Jun and Naori go on a date to a familiar location, which gives Jun flashbacks to when he was there with Rumi.

Naori explains herself and her reasons to Jun and Rumi in order, leaving them baffled.

Jun has decided not to get involved with either of them for the time being. A friend of Rumi asks Jun to help her with studying. They try to keep this a secret from Naori since she is a stunningly beautiful model.
