She thinks it's a chance to get close to Kento, but, unlike his usual kind self, Kento tries to force himself on her. When she tells him he isn't being himself, Kento discloses a shocking truth, "I'm actually Kento's twin brother, Yuto." Kento is apparently down with a cold, and Yuto took his place. Mari heads over to their apartment to help take care of sick Kento, but Yuto surprises her with his aggressive approach...! (Source: CLLENN)
