"Unnie, are you okay?" Tzuyu asks me from behind the door. I realize that I've cried too loud that she might have heard it. I wonder why she doesn't come in right away, there's no one inside the room except me.
"Mm, Nae..." I try to control my voice so it's not trembling, "Come in, dear!"
"It's locked."
"Oh right....." I wipe my eyes with my right hand while walking to the door. I open it and see the one and only member who has the same height as me. 
"Are you okay?!" She asks as soon as she sees me. Tzuyu comes into my room before even before I say anything. "What is it this time, Unnie?"
"Hehe..... Nothing. I don't know.................. Where are the others?"
"You tell me. I just woke up."
I look at her bared face and notice that. "Sana went to have lunch with the J-line... Ahh, I need to rinse my face. Hehe..."
"Tsk... Why do you cry anyway? Ohhh! By any chance....!!!"
"What?"
"Is it because Sana doesn't invite you to go with her??? Weird tho......" she guesses.
"Haha... No. Actually, I was the one who rejected her invitation. I wanted to spend time alone for now...."
"....and cry," she continues my sentences.
"And cry."

I'm going to go to the bathroom but I don't feel like it, so I get back to my bed. I look at Tzuyu sits on the other bed. It used to be an ordinary view to see her in one room with me like this. "I wanna rinse my face but too lazyyyyyyyyyyyyy!" I scream to myself.
"........"
From her expression, I think she's not in a really good mood either. She hasn't done anything since entering this room, except sitting beside me. I wonder what's her problem. '"By the way, Tzuyu, I've been noticing something," I tell her.
"What is it?"
"It's funny to know you still calling everyone by 'Unnie'. I thought the members have an agreement to call each others' names?"
"It's more comfortable this way," she answers shortly.
"But there's one person that you call her by her name tho!" I say before looking at her face. I see her turning face away a little bit from me. Her right cheek turns red. "Is she special for you?" I ask her again.
"Who are you talking about?" she asks me back.
"Ohh c'mooon! You know who~"
"Who?"
"It's Sana, riiiiggghhhhttt????" I before laughing. "Right? Right???"
"Huh?"
"Say yes, say yes, say yes!!!" I say while shaking her body. "Okaaaay..... You can keep it a secret if you want. I won't force you to tell me anything. Who am I to know all of your secrets........."
"I won't tell you anything then," she answers savagely like she usually does.
"Dammit, Tzuyu!"
"Language, Unnie!"
"Hhh..."
"Hehehe...."
"You're not fun," I say.
"I'm not. Who do you think I am? A clown?"
"Tsk... You are ruining my mood again..."
"You tease me first tho."
"You're annoying!"
"Hehehe....."
I look at her face chuckling innocently. I know she's already an adult by age, but in my eyes, she's always the maknae. I just can't angry at my beloved little sister. Uww, so cute! Ugh, I will keep my annoyed face so she doesn't know I'm fangirling inside.........

Tzuyu squints her eyes and gives me a meaningful gaze. "I have an idea, Unnie."
"Hmm?"
"To cheer you up...... Should we eat an ice cream?"
"Owww!!! From the refrigerator?"
"Let's buy it outside instead. Call?"
"Call!!!"
"Hmm, I want to take a shower first," she says.
"Should we take a shower together?" I look at her, smirking. She's stunned. is unconsciously opened a little. "It's been a while."
"It's been a while??? We never do it before."
"Then it will be our first! C'mon, this is just a shower. I just want to save time and leave this building immediately. I will be quick, anyway. What do you think?" I ask her again.
"....."
"Say yes!!!"
