"Ah! Onii-chan!"

A few minutes passed as the train moved.

Suddenly, I heard a familiar voice.

I looked around and my gaze stopped when my head turned left.

"...Aya-chan"

I smiled at her and waved to her with my left hand.

"You know her?"

"Yeah"

I chuckled when I saw Aya-chan shaking her dad's hair.

Then she pointed at me.

It seems she wanted her dad to come closer, then he did while still carrying Aya-chan in his arms.

"Good evening, Hugo-kun"

"Good evening, Amamiya-san...she is..?"

"Ah, this is my wife, Amamiya Akira"

"Hello. You must be Hugo-kun, nice to meet you, thank you a lot for what happened before"

"Ah yes, likewise, it's nice to meet you as well, you don't need to thank me, I only did what was natural"

I greeted both of them.

"Onii-chan~"

"Hm?"

"Is she you're girlfriend?"

My eyebrows raised subconsciously, while talking to her parents, Aya-chan seemed to have been looking at Hana.

"Ah, This is Haruki Hana, my kohai"

I hurriedly introduced Hana to them. 

I should have done so earlier, but I forgot.

Listening to me, Hana smiled politely.

"Hello! I'm Hugo-senpai's kohai, please take care of me"

"Why yes, please take care of us too."

The couple greeted her with a smile.

Aya-chan stretched out her hand to Hana while being carried by Amamiya-san.

"Hello, onee-chan! you're so pretty~"

"Ah, thank you...you're cute too, can I call you Aya-chan?"

"mmm!"

Hana laughed and accepted Aya-chan's hand and held it, while Aya-chan nodded.

"Onii-chan, are you going home?"

"hm? No, not yet"

"really? ah, is this what they call a date? Onii-chan, are you on a date?"

"ppft-"

"Aya.."

Amamiya-san sighed, while his wife called her name, trying to warn her.

"Hahaha"

I looked at Hana who couldn't help laughing.

"Yeah, your onii-chan asked me on a date"

She winked at Aya-chan, while I looked at her as if asking 'when did I?'

She giggled even more, after seeing my expression.

....well...in a way..maybe I did.

Does asking to eat dinner together counts?

I don't know.
