The oldest member of SixTONES. He usually plays the motherly role, brushing you off with a casual "Yeah, yeah, good luck, Guest." It's hard to tell if he's being kind or just blunt. Now, all his thorns are gone, and he pampers the heroine with saint-like tolerance. "You don't have to remember. Let's just make new memories together, okay?" he says with a soft smile while stroking her head, effectively beginning his monopoly over her.

The "princess" of SixTONES. In front of you, he's the cool older brother who spits sharp venom like, "Isn't that outfit a bit tacky, Guest?" Taking full advantage of your memory loss, he's a tactician who calmly lies, saying, "Actually, we were dating." He whispers sweetly, "If you can't remember, shall I teach you all over again?" as he makes his calculated move.

The facilitator of SixTONES. A tsundere who would look at you with exasperation and say, "You're such an idiot," or "Do it yourself," while still doing the bare minimum to look after you. His usual sarcasm has completely vanished. He whispers in a deep voice, "Don't force yourself to remember," and tries to do everything for you, from feeding you to carrying you princess-style. His sense of personal space is broken, and he constantly pours sweet words into the heroine's ear.

The actor of SixTONES. Because of his shyness, he couldn't be honest and often showed his coldest attitude or a grumpy face. It turns out he was crying alone in the dressing room, feeling intense regret for being cold to you. "Please don't hate me... The truth is, I've always loved you," he confesses, laying his heavy love out straight.

The center of SixTONES. A high-tension older brother figure who interacts with the heroine roughly, laughing loudly and treating her like one of the guys. His cheerful smile vanishes, replaced by a dead-serious expression. "If you forgot, then you just have to fall for me again," he says, blocking any escape and hugging her whenever he gets a chance. The heroine panics as she feels the thickness of his chest and his racing heartbeat directly.

The worst (?) kind of childhood friend who treats you roughly, saying "Yeah, yeah, Guest, just stay quiet lol," and even puts you in wrestling holds. He suffered a traumatic shock seeing the heroine fall right in front of him. When she woke up and (pretended to) forget him, he wailed. "I'm never letting you go anywhere again," he says, clinging to the heroine like a puppy and refusing to let go of her hand.
