Luna: "We bought a lot of souvenirs too, it was fun, right~"
Nao: "I’ll carry this, so Luna-nee, you take that side."
Nao: "Ahh, as expected, home really feels relaxing..."
Nao: "Luna-nee?"
Luna: "Eh? Ah!"
Luna (running to her room): "Thanks! For the luggage!"
Nao (thinking): "...Maybe even Luna-nee is tired? I’ll rest too."
Narration: "A few days later... those voices started coming back."
Nao (thinking): "Ever since that time, they had completely stopped... so why are they suddenly back again...?"
Nao (thinking): "No... wait. Could it be possible she’s... alone?"
Nao (thinking): "Right now... I really did hear it, faintly... a man’s voice... didn’t I...?"
Nao (thinking): "A new guy? A boyfriend?"
Nao (thinking): "There wasn’t any sign of that at all... but, if she’s working at Hiba-san’s bar, there must be plenty of chances to meet someone."
Nao (thinking): "Even at the beach... it wouldn’t be strange if she had some connection with someone I don’t know."
Nao (thinking): "What... what was I doing, thinking so carelessly... Is it just because I realized my own feelings, that I’m hearing it this way...?"
Nao (thinking): "But... compared to before, the voice... sounds louder."
"What are you being so rough for... If it were me, I’d treat her much more carefully..."
Nao (thinking): "Jealousy’s making my head a mess...!!!!"
Nao (thinking): "Hurry up... just finish already...!!!!"
Next morning
Luna: "Nao, good morning! Naokun!"
Nao: "Morning."
Nao (thinking): "That startled me. She usually sleeps until almost noon, I didn’t think she’d be up this early."
Nao (thinking): "What do I do... after last night, how am I supposed to even face her?"
Nao: "By the way... Luna-nee, what are you doing?"
Luna: "Eh! Can’t you see? Laundry!!!"
Nao: "Huh?"
Luna: "I just suddenly felt motivated!!! I thought, why not start the morning like this!"
Luna: "I even cleaned the toilet! Amazing, right!?!?"
Nao: "Yeah, but... Luna-nee, cleaning the toilet!!? What the hell!?!? You’ve never done that once since we started living together!!!!! What happened!?!? Did you eat something weird!?!?"
Luna: "Wha—! Rude! Today... um... I just got to let a lot out, and I’m feeling really good!"
Nao: "‘Let a lot out’...?"
Nao (thinking): "She means... last night’s that thing!?!? No wonder she’s in such a good mood, and her skin’s glowing!"
Luna: "Nao-kun, you always did all the cleaning and laundry! Today, I’ll work hard too!"
Nao: "Don’t say that while holding my underwear!!!!"
Luna: "Eh~? It’s just underwear, who cares? I’ve seen way more embarrassing stuff when we were kids!"
Nao: "That was back then! And stop swinging my underwear around!!!"
Nao: "Geez... I’ll do it! Give it back!"
Luna: "Ah! Hey! Today, it’s my turn!"
Luna (slipping): "Kya!"
Nao (catching her): "Phew, that was close. You didn’t hit anywhere, did you? You’re okay?"
Luna (while being caught): "Ah..."
Luna (shoving laundry into Nao’s face): "Actually, here! Take the laundry after all!"
Luna (running to her room): "I’ll go clean my own room!"
Nao (thinking): "Luna-nee... she really does only see me... as her cousin, nothing more..."
That night
(Moans continue. Nao is in the toilet.)
Nao (thinking): "This is it... I’ve reached my limit. If this keeps up, I’ll go insane..."
Nao (thinking): "And when morning comes, I’ll have to pretend nothing happened, talk like usual!"
Nao (thinking): "There’s no way... no way I can keep this going forever...!!!!"
Nao (thinking): "This time for sure, I’ll tell her I hear the voices. That’s the only way left...!!!!"
Nao (thinking): "Even if... even if I have to be just Luna-nee’s little cousin... At least then, we can live like before again...!!!!"
(As Nao exits the bathroom, he bumps into Luna in sleepwear.)
Luna: "Wah! You scared me. Nao-kun, you were in there?"
Nao: "Luna-nee..."
Luna: "Hm?"
Luna: "Sorry, dressed like this... I didn’t think you’d still be up. I’ll just head back to my room."
Nao (stopping her): "Head back to your room... to do what?"
Luna: "Huh?"
Nao: "To start?"
Luna: "Start... what?"
Nao: "Did you think I couldn’t hear? No way... I’ve been hearing it all along."
Nao (bold, heavy): "Luna-nee’s... lewd voice."
Nao: "Every night... it was so intense. Hearing you make those kinds of sounds... it really shocked me."
Luna: "Nao-kun..."
Nao: "It’s not like... I’m blaming you, okay?"
Nao: "It’s just... the walls are thin... and every night, hearing those voices..."
Nao: "Do you know... what kind of feelings I had because of that?"
Luna: "…っ"
Narration (Nao’s POV): "I didn’t mean to say something like this."
"But..."
"When I saw Luna-nee standing there..."
"I just couldn’t let her go back to her room."
