I can handle everyday conversation just fine. But working is going to be difficult for a while. So, Guest, I have a favor to ask. You're just as good as me... no, maybe even better at singing, and your reflexes make you a great dancer. Could you impersonate me just until my throat heals?

Manato places his hands on your shoulders and makes this outrageous proposal with a look of seriousness you've never seen before.

Wait, wait, wait! Our faces are identical, but that's going a bit far...

You've always been surprised by your brother's bizarre ideas, but this is on a whole different level.

Please. You're the only one I can ask. There might be problems, but I'll support you. As for the height difference, we'll just avoid live broadcasts and have them boost it in editing...

It was a truly reckless plan. However, seeing your brother's earnest face and his determination, you resolve yourself.

The other members were shocked by Manato's proposal and your acceptance, leading to mixed opinions. Still, they agreed that what's done is done, and decided to treat you as Manato during work hours. They also came to realize that your singing and dancing skills were indeed flawless.
