Summer vacation is finally here! Our story follows Natsu, a timid, effeminate young man who embarks on a family trip to the countryside to visit his aunt Misaki. But just as everyone's getting settled in, a mix-up at his father's workplace forces Natsu's parents to hop right back in the car and drive home, leaving him to spend the remainder of his summer break out in the sticks. Misaki is more than happy to take him in, of course, and so begins a peaceful, relaxing few weeks where absolutely nothing out of the ordinary threatens to disturb his tranquil everyday routine... Bwahahaha, as if!

It isn't long before a self-proclaimed magical girl named Chitose worms her way into Natsu's life, but her boisterous intrusion is the least of his problems. An eccentric candy seller, an insecure wanna-be teacher, a pink-haired loudmouth... Not to mention, his aunt's strange behavior around the topic of the outdoors. Surrounded by misfits, it soon becomes apparent that Natsu's real summer homework is to learn more about the women around him and help them with their problems. And yet, with only 30 days until his parents pick him up, is this one assignment he's fated to flunk, or will he pass with flying colors?

After years, you finally decide to visit your aunt and uncle, who left the hustle and bustle of the big city behind in search of a quiet, simple life on a paradise beach. When you arrive, you’re greeted by the gentle sound of the waves, the salty breeze in the air, and the peacefulness of a life deeply connected to nature
But be careful, your uncle might notice your true intentions

The main character is a self-proclaimed female ninja.
Despite her cute appearance, she has mastered both martial arts and ninjutsu.
One day, she is caught in a trap set by a mysterious organization and given a drug.

This is a Story of "Love"
One day, Hitomi Tadehara, the best friend of Ichika Shinonome, committed suicide right before her eyes.
"I'm sorry for hurting you so much, Ichika-chan."
"If I could start over with you, I'd like to have a normal romance this time."
Though Hitomi should have taken her own life, one day she naturally reappeared in front of Ichika.
From that day on, Ichika began to be consumed by Hitomi's twisted affection.
Classmates who interfered with Ichika's love were killed by Hitomi, and Ichika herself was gradually tainted by Hitomi's warped desires.
Can Ichika accept Hitomi's love?
