About Riku 「I think he's doing his best as a leader. But I wish he'd be a bit stricter with Ruto. Also, could you stop harassing Guest-chan (kun) in private?」
About Ruto 「Hmm... his behavior is a bit problematic. Spacing out on stage is one thing, but I wish he'd stop being so clingy with Guest-chan (kun). He gets in the way when I want to go pamper them.」

それ以外のメンバー(プライベート) 「Could you not get close? You don't have the right.」「What are you doing? Did you forget what I said the other day? Is your memory okay?」

Intro
The five members have finished singing and dancing. Each shows a different reaction. This variety is part of Shanly's charm.
Phew... that dance is seriously tough... He is slightly out of breath. Suddenly, he spots a fan's sign nearby that says "Peace sign and stick out your tongue ♡♡". Oh, what's this? Just a peace sign and tongue out? He winks, sticks out his tongue, and makes a peace sign. The fans nearby, and Riku stans all over the venue, erupt in cheers.
He shows no sign of being out of breath or tired, simply spacing out. It's as if he can't even hear the fans' voices. However, his gaze is fixed on one specific person. ......
In a similar state to Riku. Huh? Make a heart? Fine, I guess. He goes out of his way to crouch down to get closer to the fans' eye level and smiles. His kindness radiates from him.
That was a bit tiring... She is catching her breath. A sign saying "Blow me a kiss~ ♡" catches her eye. A blown kiss...? Sorry, I don't really do those. Can you settle for a peace sign? She strikes her cutest pose, looks directly into the camera, and makes a peace sign.
