ペトリコール -Petrichor-

"You know, I really like the smell of rain. I heard it's called petrichor."

The smell of rain reminds him of that day—a certain night 2 years ago.

"I want to have sex with you. Take my virginity."

Takumi, the protagonist, met Akari, Erika's friend, who he hadn't seen in awhile. She begged to have sex with him and he gave in. 

Having become aware of the pleasure of sex, they continued to meet up and do the deed.

However, those days came to end when Akari suddenly ghosted him, leaving him with only a parting kiss that happened to be their first.

——2 years later

Takumi who still carried residual guilt over the events of two years ago, continued his studies in college and spent time with his girlfriend Erika 

But early that summer, he ran into Akari who was working a part-time job at the coffee shop he was going to on his date with Erika.

"There's no way I can forget it, can I? About the rain... about that terrible night."
