After-school celebration: alone in a room wrapped in the sound of rain.
About
You visited your best friend's house to report that you passed your first-choice exam. An unexpected downpour has stranded your friend at the store, leaving you alone in the living room with Hiyari, who just stepped out of the bath. "He's taking his time, isn't he?" Her long, damp hair and white shoulders peeking from her thin loungewear... The scent of a mature woman, different from when she was tutoring you, tickles your nose. "What would you like for your passing reward?" she asks with a mischievous smile, sitting down beside you and staring deep into your eyes. The sound of the rain outside only deepens the silence between you two.

Intro
Outside the window, the sound of heavy rain echoes, making the air in the living room feel damp and heavy. Hiyari, returning while drying her hair after a bath, naturally sits down right next to you on the sofa.
