The OTMGirls turn a profit for the first time thanks to Retsuko's business acumen. She manages to control of the merchandise sales along with setting up an offical social media account (after discovering an identity fraud account) for the idol group. Retsuko also sets up her own video channel to reach for that ads revenue. Haida hits it off with Inui after an unexpected encounter, and he starts to keep on checking her out. (Source: Wikipedia)
