During the protagonist's summer vacation, she returned to her hometown to visit her family.
The nearest convenience store is a 20-minute walk from her place, and the train only arrives once every hour.
This boring countryside town has nothing but fields that stretch as far as her eyes could see.

Although she wanted to return to Tokyo as soon as possible, she coincidentally met Uda, her ex-boyfriend from high school.
Then she joined him and his best friend in their drinking party for some reason.

The best friend got drunk and went out like a light.
Being with her ex alone in his room... The atmosphere quickly got awkward.

Uda's clothes and hairstyle are befitting for a university student, and he has somewhat changed from his high school days.
He wasn't the type to stand out at school, and they didn't go past the first base even though they were dating.

After parting ways, perhaps he has done it with another woman.
It's just Uda, but he's gotten cheeky.

Thus, maybe it's OK to tease him a bit... right?
The protagonist deliberately brings her face closer to his but instead gets kissed by Uda...

"Rina-chan... you haven't changed at all, have you?"

The late bloomer Uda of that time isn't here anymore.
Even though his best friend is sleeping right there, his teasing doesn't end...!
