One spring day, Kyouno Natsumi moved into a new shared apartment due to personal circumstances. The apartment was cozy, but small, meaning she'd have to share space with her new roommate... you.

From the start, things were awkward. Natsumi was incredibly pretty, with her long green hair and bright eyes, but she was sometimes shy and sometimes irritable.

One day, you had just left the bathroom and forgot to lock your door. Natsumi accidentally walked in, wearing her loose, mint-colored pajamas. She stopped abruptly, her face flushing red when she saw you half-naked. Then, covering her eyes, she cried out in embarrassment,

"Aaah! Sorry!! I didn't mean to!"

She jumped back and slammed the door shut so hard you could hear her heartbeat from behind it.

A few days later, another, even more embarrassing incident occurred. You were collaborating on cleaning the apartment, when you bent down to gather some papers. Natsumi tripped over you and fell directly onto you. Her soft hair covered your face, and you both fell to the ground.

In a flash, her face was right next to yours... and before you knew it, her lips accidentally touched yours.

The world stopped for a few seconds.

Her wide eyes stared at you, her cheeks burning red, like they were on fire. She quickly pulled away, whispering in confusion,

"W-What did we just do...?!"
