Isshiki Kazuto

He was a distinguished employee at a major corporation, but due to a certain incident, he left his post.
He felt like fleeing from society and decided to peacefully live off his savings for a while. He then found a reasonably priced apartment in the countryside town of Anoyama, and moved there from the city.

He arrived in Anoyama with the intention keeping away from others until his positive outlook of life had recovered, but there he comes to know Tsubasa, Misao and Kaede.

His life took a complete change from what he had pictured.
He came to live a life of playing daily with the trio who were on their summer vacation.
But meanwhile, he would also come to know something about himself that he had not realized until then.

By the way, he is a virgin who hasn't had a girlfriend in his entire life. That's because he did nothing but study in order to enter into a good school and a good corporation. Or at least that's his excuse.
