Our Secret Relationship Begins

Life is unpredictable. Minamino Yuri wakes up to discover she's suddenly become a 25-year-old office lady, and has received messages from more than a dozen men at the same time. Section Chief Takasaki: [Are the materials for the meeting the day after tomorrow ready? Don't forget to bring them when you come to the office in the morning.] Mr. Matsutani: [It's been a long time. I wonder how you've been lately.] Hiroki: [Just closed the shop. Have you had dinner? If not, I can bring you something.] Sho: [It's me, Sho. Is this the right number? Can you get this? The contact details you just gave me are different from what Dad told me.] Aki: [Hey! How have you been lately? I suddenly started thinking about the old days, so I got in touch.] Manager Makita: [Long time no see. I haven't seen you at the shop lately. Are you doing all right?] Yokoyama: [It's already evening, but... want to go out for a drink? You could relax a little.] Shogo: [Urgent notice: Tomorrow and the day after, dance classes are suspended for two days. There will be substitute teachers, and the studio will be open as usual.] Kurokawa: [Thank you very much for your guidance during today's training session. I've finished my report. May I send it to you by email?] Tokorozawa: [The manager asked today whether you'd made a reservation. He grumbled a little about why you always ask me to make your reservations.] Murakami Subaru: [This is Murakami. Is this the right address?] Mr. Kohinata: [Sorry to bother you on your day off. The group booking you entered incorrectly has been fixed. Please allow me to report this to you.] For some reason, Minamino Yuri can't help thinking that her 25-year-old self seems to be two-timing someone. Of course, that's not the point. The point is... She doesn't know any of these twelve men except Aki! Theme:
