"Look who's here!"

I can hear a familiar voice from someone behind me. In front of one of the sinks, Sana's standing there looking at me. 
"Are we really destined? I was just gonna find you, Juju," she says.
"What do you want, Sana?" I ask as I'm walking towards her.
She tilts her head and looks at my face. It seems like she doesn't know a personal zone.
"What's wrong?" I ask her.
"Nothing," she says.
"Uhh, I shouldn't be here, actually. I think I'm just gonna leave. If you don't mind-"
"Wait!" she cuts me and grabs my right hand, "Follow me," she says as she's pulling me to the corner of the room. I can see her scanning the room for a moment. Currently, there's just one girl washing her face beside the two of us.

"Haeju," Sana puts her hands on my cheeks, turning my head so I face her. Her hands are kinda cool but gentle. I don't realize it before but I can smell a jasmine scent from here.
"Yes?"
Sana looks at me weirdly. She stares focused at my lips. Her eyes are gloomy. She's breathing heavily. I can't help but also looks at her lips as I'm taller than her. Her lips are a little bit apart. They're pink and glossy. Maybe she's using a-

Without a command, Sana pulls me gently and kisses me. I'm so surprised! I keep my eyes opened but she's not. She's closing her eyes and I think she's enjoying it. My heart skips a beat. I grab both of her wrists. I feel connected.

She releases me and opens her eyes.  "Ju... Can I be your prom date?" she asks me.

I can see the girl from before hurriedly left us both here. She's leaving the restroom.

I look at Sana again and say, "You're saying?"

Quickly we kiss again. I close my eyes this time, I think. I try to enjoy her lips this time. It's soft and wild. So intense. Sana's hand is grabbing my school's uniform while my hands are holding her upper arms. I peek a little bit to see a pretty girl that I'm kissing right now. She lets apart and I follow her lead. Slowly but sure, we're kissing more deeply. Oh, I never know I can experience happiness, love, nervousness, and fear at the same time. She gives me the feels.

I feel lost when she stops our activity. I can see she's so passionate, but then that expression suddenly changed when sees something behind me. Her eyeballs come out like she's looking at a ghost. I turn my head and see Tzuyu just standing there. Watching us.

Without expression. Without words. I don't know why she's looking at us like that. Not gonna lie, it's kinda weird.

"Aaa! What a creep!" Sana screams. She pulls me again towards the door, "Let's go out of here, Juju!" she says while staring at Tzuyu. The latter is standing still as we pass by her. Oh wait, I think her eyes are teary.

Why is Tzuyu like that?
