OVERVIEW
The protagonist, Tomoki Motosu, is living with his girlfriend, Saori Kawakita, and is considering proposing marriage.
One day, however, he is shocked to hear from their mutual childhood friend, Souta Nonomiya, that he is suffering from a disease and has no idea how long he has left to live. The two of them vow to help him in any way they can, and bring him home to live with them.
When Tomoki hears Souta’s wish to touch a woman before he dies, he consults with Saori and decides to make his wish come true. At first, Saori gives him a blowjob. Eventually, however, she allows him to have sex with her as well. For Tomoki, although he was jealous of having his girlfriend embraced, he remembered how it felt like when they used to play together.
However, when Souta’s condition did not progress even after some time had passed, he began to feel some skepticism in his joy. Then, he witnesses Saori being embraced by his friend without telling him.
From that point on, the three of them begin to drift apart…
